Phase Shift control of Bidirectional H-bridge DC-DC Converter

Phase-shifting control is used in bi-directional full-bridge DC-DC converter, study on its working principle , transmission power, soft switching range, power reflux phenomenon and the productiveness of the converter has reduced, through the converter power transmission equivalent model, converter analysis can realize the ZVS scope under necessary conditions, and ultimately simulation to verify the converter forward transmission power. The converter can achieve ZVS with obvious reactive circulation power and high voltage side switching tube, but the switching tube in the low voltage side bridge cannot achieve zvs. The performance index of the converter is simulated and studied.
