This paper proposes a two - armed push - pull inverter , including its topologies , power distributions in every switching devices and modulation schemes . the major parameters such as thd and df of this vsi are analyzed . comparison study shows that the quality of two - armed push - pull vsi is better than those of square - wave vsi . and the switching loss is lower than that of pwm scheme at same time , especially used in wide frequency range . detailed calculating formulae and experimental results are presented
该文介绍了一种双臂推挽式逆变器,包括其电路拓扑、每个开关器件的功率分布和调制策略.分析了这种电压源逆变器的主要参数,如总谐波失真度( thd )和失真指数( df ) .比较研究表明,这种逆变器的质量明显优于方波逆变器,同时开关损耗明显低于pwm调制方式,特别适用于宽频范围.介绍了计算公式和实验结果
