N2 - A novel high switching frequency isolated voltage-fed hybrid bridge combining semiactive rectifier dc-dc converter is introduced for unidirectional power flow and wide voltage gain. Three potentially appropriate working patterns are elaborated, including ideal output power derivation, current stress analysis, working voltage matching, output power distribution, soft switching characteristics, etc. In consideration of the optimization of the minimum of the root-mean-square value of the leakage inductor current, two truly applicable working patterns are selected. Meanwhile, based on the consideration of soft switching, a segmented control strategy is implemented on it. With the optimization of current stress and the realization of soft switching, the converter can theoretically realize higher efficiency operation. Eventually, the effectiveness of the proposed converter and the control strategy is verified by a 1 kW prototype.
