车载正弦波逆变器的设计与实现

摘要

Inverter input the DC 12V for the car battery,the output terminal of sine wave is 220V.Then system will take DC/DC high frequency booster and DC/AC inverter two-stage structure .When the direct voltage is through push-pull transformation by the high frequency transformer booster then get a 330V voltage rectifier filter,after wave of bridge transformation ,finally,the sine wave of voltage is 220V.%逆变器输入为汽车蓄电池DC 12 V电压，输出为工频正弦波220 V电压。系统采用DC/DC逆变高频升压和DC/AC逆变两级结构。12 V直流电压通过推挽式变换逆变为高频方波，经高频升压、变压器升压和整流滤波得到一个330 V电压，再经过桥式变换以方波逆变的方式最终得到正弦波交流220 V电压。
