Impulse commutated chopper
Witryna26 lut 2024 · Voltage-commutated chopper is one of the simplest and earliest chopper circuits. This chopper is generally used in high power circuits where load fluctuation is not very large. This chopper is also known as Parallel Capacitor Turn Off Chopper, Impulse Commutated Chopper or Classical Chopper. WitrynaAn inductive load is controlled by an impulse commutation chopper in Fig.1 and peak load current IL-450A at a supply voltage of 220V. The chopping frequency f=275 Hz, commutation capacitor C=60μF and reversing inductance Lm-20µH.The source inductance Ls=8µH, determine: a) peak Capacitor discharge Current.
