快速过零逆变交流方波电源研制

Study on Quick Response AC Square Wave Inverter Power Source

介绍了ＭＯＳＦＥＴ交流方波逆变电源的工作原理。设计制作了快速过零逆变交流方波电源，在设计中，采用了与以往的逆变系统不同的主电路结构，并因此而简化了逆变控制电路。通过实验证明，所设计的快速过零逆变交流方波电源过零速度极快，大大提高了小电流时电弧稳定性，且整个系统结构简单，可靠性高。

Introduce the principle of MOSFET AC square wave inverter power source. Design a quick response AC square ware inverter power source, adopt new main circuit structure different from old inverter system. So the inverter control circuit is simplisfied,the tests prove that the speed of the quick response AC square wave power source is high, the arc stable property in small current is raised greatly ,and the structure of system is simple, the stability is high.
