Chopper

A buck converter is a dc to dc step-down converter or step-down chopper that lower the magnitude of the applied dc input signal at the output side.

A step-up chopper is similar to a step-up transformer whose output voltage is greater than the input supply voltage. The below shows the circuit configuration of the step-up chopper.

The chopper circuit employing the load commutation technique is known as the load commutation chopper. The load commutation technique is, falling

The current commutated chopper is a type of forced commutated chopper that uses an oscillatory current in order to turn OFF the main thyristor.

In voltage commutation, a reverse voltage is applied across the thyristor using a charged capacitor. So that conducting thyristor reverse-biases and

An ac chopper is a static switch that uses semiconductor devices for the variation of the ac voltage. It is also known as ac to ac chopper. This type of chopper is widely used in induction

A Step-down chopper is basically a high-speed semiconductor switch. The switch can either be a power BJT, power MOSFET, transistor, or SCR depending
