Chopper

A chopper is used to obtain controlled dc output from an unregulated or fixed dc input with minimal power loss. It is a solid-state switching device

The Morgan chopper is a single SCR chopper that employs class B commutation or current commutation or resonant pulse commutation. The Morgan chopper

Jones chopper employs class D commutation to turn off the main thyristor. Here, a charged capacitor is switched by the auxiliary thyristor in order to
