Popis:	Forced commutation schemes have been used in two-pulse converters in order to improve the power factor. Such a scheme also increases the regenerative power. A bridge converter with transformer-coupled forced-commutation circuit is proposed in this paper. The commutation process is analysed and normalized turn-off time curves are presented. The effect of load current on the commutation process is discussed. The proposed converter configuration is useful for both motoring and regenerative operations of series as well as separately excited DC motors. The results are experimentally verified.
