【 摘 要 】

The Asymmetrical Half Bridge Converter (AHBC) realizes Zero-Voltage Switching (ZVS) of the switches by using its parasitic components in the circuit. The AHBC can get good input and output performances without much change in the whole circuit or large increase in the costs. In the paper, the average circuit model of the power stage and the small signal model of control circuit for AHBC are established by means of state-space-averaging method, the dynamic characteristics and stability are analyzed, and the compensator is designed. Finally, the stability and dynamic performance of the converter are verified by MATLAB simulation.
