A Soft-Switched Semi Dual Active Half Bridge Converter With Voltage Match Trapezoidal Modulation Control

To address the demands for a wide voltage range and high efficiency in unidirectional low power applications, a semi dual active half bridge (DAHB) converter with soft switching capability and a voltage match trapezoidal modulation (VM-TZM) control are proposed. This converter has the fewest number of active switches among existing dual active bridge converters. With the proposed control law, the converter always works under voltage match condition, effectively decoupling the control variables while achieving low root-mean-square current. Besides, the active switches can realize zero-voltage-switching (ZVS) on and the diode can obtain zero-current-switching (ZCS) off within full working range. These characteristics and benefits of the proposed converter and control law are validated through an experimental prototype.
