A modified one cycle control(OCC)based bidirectional half-bridge AC-DC converter was proposed.Compared to the conventional OCC based converter which fails to operate in inverting mode,the proposed converter could operate stably in both rectification and inverting mode,thus bidirectional power flow with high power factor was realized,operation principles of the proposed half-bridge AC-DC converter were presented and analyzed,and the stability criterion along with the voltage balance of the bridge capacitors ...
