Impulse commutated chopper

WitrynaAll chopper circuit semiconductor static and dynamic electrical requirements plus motor losses can be determined for any imposed mechanical load conditions. A current-impulse commutated dc chopper/controlled compound motor simulation is presented and results correlate excellently with those obtained experimentally. Witrynawritten 3.8 years ago by teamques10 ★ 49k. The DC Choppers convert the input DC voltage into fixed or variable DC output. Hence DC chopper is also called as dc to dc converter. The output V o can be greater or lesser than the input. Hence the chopper can be step-down or step-up type.
