Study of a Half-bridge Converter of Single-stage PFC

The paper discussed a half-bridge converter of single-stage PFC with ZVZCS.By the application of suitable selection of the circuit parameters,this converter could work as the operation mode of soft switch in a very high efficiency,and keep the simple topology as well.The working principle was(explained) and analyzed in detail,and the correlative design parameters were provided too.The simulation experiment by Matlab showed that the working principle of the converter is feasible.
