Abstract :
A novel PWM AC-DC converter is proposed, based on a `current source inverter´ topology, for use as a bulk supply source for DC power reticulation systems. The switching control is based on a modified space vector modulation technique, using twelve nonzero space vectors rather than the usual six. Control of DC side voltage is accomplished in discrete time at the converter switching frequency, using a minimum-time approach for high performance. The discrete-time controller provides voltage commands to the converter, which determines a PWM switching sequence for the next sample period. Performance of the converter is demonstrated in simulations
