三逆变桥的组合逆变/充电器主电路设计

Design a Inverter/Charger Circuit of Three Inverter Bridge

在单个逆变桥的基础上,为了获得输出波形接近正弦波的阶梯波,设计了一个新颖的逆变/充电器,其最大特点是3个逆变电路的输出各通过一个变压器进行升压,且3个变压器串联输出。通过控制MOS-FET的通断,输出是一个接近正弦的阶梯波。再通过简单的滤波,最后得到非常好的正弦波。

In order to get obtaining output of wave adjacent sinusoid ladder of wave above single power inverter,a novel power inverter/charger was designed, which maximal characteristic is consist of three inverter circuit output by three series-wound transformer hoist voltage. Through controlling MOSFET break on or break off,a adjacent sinusoidal ladder of wave is got. And by a simple filter, a good sinusoidal wave is obtained.
