These devices are generally represented by a switch. Chopper is “on” or “off” semiconductor switch having high speed. When Switch is “off” no current flows through it. When the switch is “On” current flows through the circuit. Fig-1: DC Chopper Circuit And Waveforms

WebClass B: Self commutated by an LC circuit; Class C: Cor L-C switched by another load-carrying SCR; Class D: C or L-C switched by an auxiliary SCR; Class E: An external pulse source for commutation; Class F: AC line commutation; Class A: Self Commutated by a Resonating Load. Class A is one of the frequently used thyristor commutation techniques. WebFig. 2.15: First quadrant Chopper - Output Voltage and Current Waveforms. Class A Chopper is a step-down chopper in which power always flows from source to load. It is used to control the speed of dc motor. The output current equations obtained in step down chopper with R-L load can be used to study the performance of Class A Chopper.
