摘要
Abstract
The type of North American domestic distribution voltage is two phase three wire,which consist of two live wires having phase difference 180 ° and one neutral wire. Gird connected inverter applied to this voltage is also confronted with unbalance load. And then,three level structure with DC link midpoint connected to neutral point is adopted to restrain common mode voltage of non insolated grid connected inverter. The method of the outer DC voltage loop and the inner inverter current loop was adopted,which adding load current feed-forward,to achieve stabilization of DC link voltage and track of unbalance load current. Then,proper method was adopted to stable DC link midpoint voltage. The control method is validated by the simulation and experiment.关键词
