The main circuit structure was simple and the two main power tubes switched into conduction alternatively to reduce the input and output voltage and current ripple. High-frequency transformers can achieve electrical isolation for input and output with the characteristics of high efficiency and high reliability. This circuit application improved the performance index of Inverter circuit in possession of practicability and engineering application value.
