摘　　要：理论上分析了串联谐振逆变器中死区处于不同位置时的工作过程 ;论述了不同死区宽度对逆变器换流过程的影响 ;提出了一种最佳死区的选择方法 。Working process of the series resonant inveter is analyzed respectively when dead time and current of the load locate at three different phase.Influence of dead time breadth on switching loss is discussed.A method for choosing the best dead time is presented.The method indicates the best dead time breadth with formula and describes suitable phase between dead time and current of the load.Validity of the method is proved by experiment.
