摘要
Abstract
This paper analyzed the requirement of the control of intermittent pulse high-power inverters in parallel, studied the master-slave pulse synchronization control strategy, so a combination method of master-slave control and distributed control on inverters in parallel was proposed. Relationship is derived by Laplace Transform Method between circulation current and circuit loop inductance, pulse time difference, etc. The time difference of pulses between the master and slaver is suppressed under micro-second level, the same time, the circulation loop cable inductance is increased to suppress circulation. It's proved effectively on improving power level and power sharing between inverters in parallel in this method. Experimental results show that this method can suppress circulation current effectively, and considerable current sharing performance can be achieved on inverters in parallel.关键词
