Chopper Circuit : Working Principle, Types and Applications
https://www.elprocus.com/a-brief-introduction-to-chopper-circuits/
Chopper Circuit Principle of Operation. The principle of operation of chopper can be understood from the circuit diagram below. The circuit consists of a semiconductor diode, resistor, and a load. For all type of chopper circuit, the output voltage value is controlled by periodic closing and opening of the switches used in the circuit.

Chopper type amplifier topologies have existed for decades. Initial chopper designs actually involved switching the AC coupled input signal and synchronous demodulation of the AC signal to re-establish the DC signal (see Figure 2-116).While these amplifiers achieved very low offset, low offset drift, and very high gain, they had limited bandwidth (it is a sampled system after all) and …

The circuit that is designed to directly convert fixed dc voltage into variable dc voltage is called Chopper Circuit. It is also known as dc to dc converter or dc chopper. Choppers are considered to be dc equivalent to ac transformers, the reason for the same is that similar to the transformers, choppers hold the ability to step up or step down the fixed dc input voltage.

Step – up Choppers . In the case of the chopper circuit (Refer figure named – “chopper circuit”) shown in beginning of this article, V 0 or the average output voltage is less than the input voltage V s so this type of chopper is called a step down chopper.

A basic chopper amplifier circuit is shown in Figure 1 below. When the switches are in the "Z" (auto-zero) position, capacitors C2 and C3 are charged to the amplifier input and output offset voltage, respectively. When the switches are in the "S" (sample) position, VIN is connected to

Type D Chopper or Two-Quadrant Type –B Chopper Two Quadrant Type B chopper or D Chopper Circuit. The circuit diagram of the type D chopper is shown in the above figure. When the two choppers are on the output voltage v 0 will be equal to V s . When v 0 = – V s the two choppers will be off but both the diodes D1 and D2 will start conducting.
