What Is Voltage Multiplier With AC Voltage Training Boards?

“Voltage multipliers are special devices designed for AC-to-DC power conversions”. They include capacitors and diodes to turn out potential DC voltage sourced from a low-voltage AC outlet. Multipliers comprise several stages, and each of them has a capacitor and a diode. 

The proper setup of capacitors and diodes helps produce filtered and rectified output. The amplitude of the voltage is higher compared to the input voltage.

The voltage multiplier had its origin in 1932. Primarily, it was essential for applications that needed low currents and high voltages. With the use of multipliers, the transformer size can be reduced.

Working Principle Of Voltage Multipliers With AC Voltage

Voltage multipliers with AC voltage are electrical circuits that use a combination of capacitors and diodes to increase the voltage of an alternating current (AC) input. The working principle of these circuits is based on the ability of capacitors to store electrical energy and the rectifying properties of diodes.

A typical voltage multiplier circuit consists of a series of diodes and capacitors connected in a specific configuration, known as a “multiplier network.” 

• The input voltage is applied to the first diode-capacitor pair, also referred to as a “stage.” The diode in the stage rectifies the input voltage, allowing current to flow through the capacitor and charge it to the peak value of the input voltage.
• The charged capacitor then serves as the input for the next stage, and the process repeats. The voltage across each capacitor increases as the input voltage is applied to each successive stage. The final output voltage is the sum of the voltages across all the stages.

This circuit is also known as a cascade voltage doubler, as it doubles the input voltage at each stage. The number of stages in a multiplier circuit determines the overall multiplication factor of the circuit. For example, a circuit with two stages will have a multiplication factor of 2, while a circuit with three stages will have a multiplication factor of 3.

It’s worth noting that voltage multipliers with AC voltage can only be used with AC input voltage, as the diode rectification process relies on the alternating nature of the input voltage. The output voltage will also be an AC voltage with the same frequency as the input but with a higher amplitude. 

Components Of Voltage Multipliers With AC Voltage Training Board?

A voltage multiplier with an AC voltage training board is designed for educational and training purposes, it typically includes various components that allow students and engineers to learn about, build, test, and troubleshoot voltage multiplier circuits.

1. Diodes- 

Diodes are one of the critical components of voltage multiplier circuits; they rectify the input voltage and allow current to flow through the capacitors. Training boards often include various types of diodes, such as silicon, germanium, and Schottky diodes; this allows students and engineers to experiment with different types of diodes and understand their characteristics.

2. Capacitors- 

Capacitors are another essential component of voltage multiplier circuits; they are used to store electrical energy. Training boards typically include various types of capacitors, such as ceramic, electrolytic, and tantalum capacitors, to allow students and engineers to experiment with different types of capacitors and understand their characteristics.

3. Beadboard- 

A breadboard is a device that allows students and engineers to build and test electronic circuits without having to solder components together. Training boards often include a breadboard to allow students and engineers to build quickly and test voltage multiplier circuits.

4. Power Supply-

These are standard components found on voltage multipliers with AC voltage training boards. The components included on a training board will depend on the specific board and the intended use.

Voltage Multipliers With AC Voltage Training Board Setup

The main setup of a voltage multiplier includes capacitors and diodes. A training board setup for voltage multipliers would typically include the following components:

• A power source (such as a transformer) to provide the input voltage
• Diodes (such as rectifier diodes) to convert the AC voltage to DC
• Capacitors store and release energy to increase the voltage
• A load (such as a resistor) to measure the output voltage
• Connecting wires and breadboard or PCB to connect the components
• A voltage meter or oscilloscope to measure the input and output voltages

The number of capacitors and diodes varies with the type of multiplier circuit you have chosen. They receive the low-value AC voltage for a successful conversion into high-value DC voltage. That is why a voltage multiplier circuit can multiply and rectify the voltage. There are diodes to facilitate the rectification process. On the contrary, the capacitor plays a role in increasing the voltage. 

Some voltage multipliers include voltage doublers (found in a cross-coupled type of capacitor). Other multipliers show low power conversion capability. It is because their input voltage becomes low.

Depending on the type of multiplier, you can achieve the dual polarity output by joining negative and positive terminals. The voltage multiplier alternately switches the output between the voltage doublers.

You can read the brochure available with the voltage multiplier package to learn more about the setup. 

Types Of Voltage Multipliers With AC Voltage Training Board-

Voltage Multipliers With AC Voltage are of different types-

1. Have-Wave Voltage Doubler-

A half-wave voltage doubler is a circuit that uses diodes and capacitors to double the amplitude of an AC voltage. It works by rectifying the input voltage and using the capacitors to store and release energy during the positive half of the input cycle.

• The circuit consists of two capacitors, two diodes, and a load. The input voltage is applied to the anode of the first diode, which allows current to flow through the diode during the positive half of the input cycle.
• The current charges the first capacitor, and the voltage across the capacitor is added to the input voltage, resulting in a doubled voltage at the output.
• During the negative half of the input cycle, the second diode becomes forward-biased, allowing the current to flow through it and charge the second capacitor. 
• The voltage across the second capacitor is also added to the input voltage, further increasing the output voltage.

The circuit is inefficient as a lot of energy is lost as heat. The output voltage is also not completely stable and can vary depending on the input voltage and the capacitance values used in the circuit. Additionally, the voltage doubler circuit is only designed for half-wave rectification, so if the input is a full-wave, the circuit will not work.

Usage of Heat-Wave Voltage Doubler- 

Half-wave voltage doublers are widely used in older electronic devices such as tube-based radios, televisions, and industrial equipment requiring a high-voltage DC supply.

Half-wave voltage doublers can be used when a high-voltage DC supply is needed, but the input voltage is low or unstable. They are also helpful in cases where the cost of a full-wave rectifier or a more sophisticated voltage multiplier circuit is not justifiable.

In addition to these, they can also be used in specific experimental setups, such as high-voltage DC generators, and in some educational labs to demonstrate how voltage multipliers work.

It is worth noting that, in most cases, modern electronic devices and equipment use more efficient and stable power supply circuits, such as full-wave rectifiers or switching power supplies.

2. Full-Wave Voltage Doubler

A full-wave voltage doubler is a circuit that uses diodes and capacitors to double the amplitude of an AC voltage. It works by rectifying the input voltage using a full-wave rectifier circuit and using the capacitors to store and release energy during both the input voltage’s positive and negative half cycles.

The circuit consists of four diodes, two capacitors, and a load. The input voltage is applied to the anode of the first diode and the cathode of the third diode, which allows current to flow through both diodes during both the positive and negative half cycles of the input voltage. The current charges the two capacitors, and the voltage across each capacitor is added to the input voltage, resulting in a doubled voltage at the output.

Full-wave voltage doublers are more efficient than half-wave voltage doublers as they utilize both positive and negative cycles of the input voltage. They also provide a more stable output voltage compared to half-wave voltage doublers. However, they are still not as efficient as other power supply circuits, such as a full-wave bridge rectifier or a switching power supply.

Full-wave voltage doublers are used in specific applications, such as powering tube-based devices, high-voltage DC generators, and industrial equipment requiring a high-voltage DC supply. They are also used in some educational labs to demonstrate how voltage multipliers work.

Usage of Full-Wave Voltage Doubler- 

A full-wave voltage doubler is a circuit that can be used when a high-voltage DC supply is needed, but the input voltage is low or unstable. Some specific applications that can use full-wave voltage doublers include:

• Powering Tube-Based Electronic Devices:

• High-Voltage DC Generators:

• Industrial Equipment: 

Some industrial equipment that requires a high-voltage DC supply can use a full-wave voltage doubler as a power supply circuit.

• Educational Labs: 

Full-wave voltage doublers are also used in some educational labs as a demonstration of how voltage multipliers work, and to teach students the basic principle of full-wave rectification.

It is worth noting that, in most cases, modern electronic devices and equipment use more efficient and stable power supply circuits, such as full-wave bridge rectifiers or switching power supplies. Full-wave voltage doublers are not widely used in modern applications due to their poor efficiency compared to other power supply circuits.

3. Voltage Tripler-

A voltage tripler is a circuit that uses diodes and capacitors to triple the amplitude of an AC voltage. It works by rectifying the input voltage and using the capacitors to store and release energy during the positive half cycles of the input voltage.

The circuit consists of six diodes and three capacitors. The input voltage is applied to the anode of the first diode, which allows current to flow through the diode during the positive half of the input cycle. 

The current charges the first capacitor, and the voltage across the capacitor is added to the input voltage. Then the second diode is used to charge the second capacitor, and the voltage across the second capacitor is added to the input voltage and the first capacitor voltage. 

Finally, the third diode is used to charge the third capacitor. The voltage across the third capacitor is added to the input voltage and the first and second capacitor voltage. The output voltage is the sum of the input and voltage across the three capacitors, resulting in a tripled voltage.

Usage of Voltage Tripler- 

Voltage triplers are widely used in specific applications, such as powering tube-based electronic devices, high-voltage DC generators, and some industrial equipment requiring a high-voltage DC supply. 

4. Voltage Quadruple-

The current charges the first capacitor, and the voltage across the capacitor is added to the input voltage. Then the second diode is used to charge the second capacitor, and the voltage across the second capacitor is added to the input voltage, the first capacitor voltage, and so on. 

The output voltage is the sum of the input and voltage across the four capacitors, resulting in a quadrupled voltage.
