| Abstract: | Asymmetrical Half-Bridge Converter(AHBC)can take use of the parasitic components in the circuit and realize Zero-Voltage Switching(ZVS)of power devices.The AHBC can get good input and output performances without much change in the whole circuit or large increasing in the costs.This paper presents the small-signal model,dynamic analysis,simulation study and the feedback compensation design of the AHBC,and makes study on its stability and performance in frequency domain. |
