后备式方波输出逆变电源中转换电路的设计

Design of Shift Circuit in Reserve Square Wave Output Inverter

本文提出了一种实现后备电源输出方波与正弦波之间切换的方法,给出了实用的硬件电路和软件框图,从而使转换电路的可靠性显著增加。

This paper proposes a method of shift between square wave and sine wave from reserve supply and gives practical hardware circuit and software block diagrams. Reliability of shift circuit is increased markedly.
