摘要
Abstract
A deadbeat and coordinate control for zero-sequence circulating currents suppression in multi-parallel inverters was proposed. First,the model of zero-sequence circulating current in the N-paralleled inverters was derived. It was shown that the circulating current was not only susceptible to the mismatches of circuit parameters ,but it was also influenced by the interactions of circulating current controllers used by other paralleled inverters. To eliminate these zero-sequence circulating currents,a coordinate and deadbeat control strategy for N-paralleled inverter was proposed. Zero-sequence circulating currents were suppressed by adjusting the dwell time of zero vector. An effective mitigation of circulating current is demonstrated for the paralleled inverters under the unequal output currents conditions.关键词
