摘要
This paper presents output power characteristic of a unidirectional Secondary-Resonant Single-Active-Bridge (SR-SAB) DC-DC converter with isolated high-frequency transformer. In the SR-SAB converter, the secondary H- bridge converter of the Dual-Active-Bridge (DAB) converter is replaced with the diode rectifier circuit, in which each diode has a resonant capacitor in parallel. The voltage and current waveforms of the SR-SAB converter in the rated condition are similar to those of the DAB converter. The authors propose the output power control of the SR-SAB converter that changes the pulse width of the primary voltage. The effectiveness of the proposed output power control is verified by experiments.
