Due to the lower and significantly fluctuating voltage of micro-source modules (e.g., photovoltaic and fuel cells) in DC microgrids, there is a need for a DC-DC converter with a high gain and a high efficiency to serve as an interface circuit. Therefore, a novel active switched capacitor DC-DC converter based on an isolated Sepic topology is proposed. This converter reduces voltage spikes on the switch tube caused by leakage inductance through a clamp circuit and employs multiple boost units to achieve a high voltage gain. In addition, it also has advantages such as electrical isolation, low stress on the main switch tube and passive clamping. The operation modes and boosting mechanism of the proposed converter are studied, the component stresses are analyzed, and the efficiency of this converter is derived. Finally, a 200 W prototype was constructed in the laboratory to verify its performance.
