摘　　要：介绍了四桥臂三相逆变器的结构 ,其三相负载可以是平衡的或不平衡的、线性的或非线性的。由于第四桥臂的加入 ,控制变得复杂。提出了一种最大误差电流调节方案 ,该方案易于实现并能带任意负载。The structure of three phase inverter with four bridge legs is introduced, its load could be an arbitrary load, e.g. unbalanced and/or balanced load, linear and/or nonlinear load. With the additional neutral leg, system control becomes complex. A kind of maximum error current regulated method is proposed, it is easy to realize and can work under arbitrary load condition. Experiment result confirm its validity.
