介绍了一种新型DC／AC变换器的拓扑结构。仅在增加一个功率器件的基础上能够实现功率开关的软开关工作方式，较好地解决了此类电路中的EMI、开关损耗过大等问题，使逆变器的开关频率从10kHz左右提高到30kHz以上。
The topology of a new DC / AC converter is introduced. Only the addition of a power device based on the power switch can achieve the soft switch mode of work, a better solution to such circuits EMI, excessive switching losses and other issues, the inverter switching frequency from about 10kHz to Above 30kHz.
