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. Witryna1 sty 1984 · The techniques for determining the chopper losses are described. The losses of two commutation circuits are evaluated and compared with those of gate-turnoff thyristor chopper for same drive specifications. The relative advantages of the gate-turn-off chopper as compared to the forced-commutated choppers are …
