Choppers are DC - DC converters. They find application in modern power electronics. They are being used in dc motor speed control and other similar applications. This course is about choppers. Main classification of chopper circuits, commutation methods as well as chopper output voltage control methods are discussed. Classification of chopper circuit includes two different classifications. One is  based on direction of output voltage and current. Second one is based on input and output voltage levels. Different commutation techniques are also discussed.

Overview Lesson

Chopper classification based on direction of output voltage and output current. There are five different classes based on their quadrant of operation.

Chopper Classification 1

Chopper classification based on input and output voltage levels. It's classified as buck converter, boost converter and buck- boost converter

Chopper Classification 2

Voltage commutation, current commutation and load commutation are discussed in detail.

Commutation in Chopper Circuits

Forced commutation techniques in choppers are discussed. That includes class A commutation, class B commutation, class C commutation, class D commutation and class E commutation.

Forced Commutation Methods

Chopper output voltage control methods are discussed. That includes constant frequency control, variable frequency control and current limit control.
