Chopper Circuit : Working Principle, Types and Applications
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.

Jun 11, 2016Morgan Chopper : The circuit diagram is as shown in figure. This circuit has only one thyristor. The special feature of this circuit is the saturable reactor (SR). The commutation circuit is formed by the capacitor, saturable reactor SR and the diode D1. Assume that the exciting current of the saturable reactor is negligibly small.
Types of Chopper Circuits - Type A, Type B, Type C, Type D
Jul 27, 2017The 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.
Chopper (electronics) - Wikipedia
In electronics, a chopper circuit is used to refer to numerous types of electronic switching devices and circuits used in power control and signal applications. A chopper is a device that converts fixed DC input to a variable DC output voltage directly. Essentially, a chopper is an electronic switch that is used to interrupt one signal under the control of another. In power electronics applications, since the switching
