Voltage Multiplier Circuit Design Circuit Diagram The voltage doubler is a type of the voltage multiplier circuit. Most of the voltage doubler circuits with few exceptions can be viewed in the form of a higher order multiplier at a single stage. Also, a greater amount of voltage multiplication is achieved when there are cascading identical stages which are being used together. Villard Circuit Circuit of Voltage Multiplier. The circuit of a simple voltage multiplier is shown in Figure-1. It is clear that a voltage multiplier is simply a combination of diodes and capacitors. The low voltage AC signal is input to the circuit from the power source (transformer in this case). This AC voltage is converted into DC voltage by diodes and
The most commonly used multiplier circuit is the half-wave series multiplier. All multiplier circuits can be derived from its basic operating principles. Thus, the half-wave series multiplier circuit is shown in Figure 1 to exemplify general multiplier operation. The example shown in Figure 1 assumes no losses and
Circuit, Operation, Types, and Applications Circuit Diagram
So how does it work. The circuit shows a half wave voltage doubler. During the negative half cycle of the sinusoidal input waveform, diode D1 is forward biased and conducts charging up the pump capacitor, C1 to the peak value of the input voltage, (Vp).Because there is no return path for capacitor C1 to discharge into, it remains fully charged acting as a storage device in series with the
the dimension of voltage as shown in Figure 1. Figure 1: Basic Analog Multiplier and Definition of Multiplier Quadrants . From a mathematical point of view, multiplication is a "four quadrant" operationโthat is to say that both inputs may be either positive or negative, as may be the output. Some of the circuits

A voltage doubler provides a means of obtaining a wider VCO tuning range at lower voltages. This paper dis-cusses the considerations that need to be made when using a voltage doubler. Specific test results are shown for a CDMA application. The LMX2350 provides an internal switched capacitor volt-age doubler circuit that allows the RF charge Voltage Multiplier Circuits are devices that are designed to generate an output voltage that is a multiple of the input voltage. They are often used to achieve higher voltage levels than older circuits that were developed in the past, especially in situations where efficiency and compact design are very critical.
