High-Gain Switched-Capacitor DC-DC Converter With Low Count of Switches and Low Voltage Stress of Switches

This paper presents a novel concept of high-voltage-gain DC-DC converter. The converter is made up switched capacitors and passive resonant branches. A significant reduction in the count switches low voltage stress on achieved this proposed topology, comparison to that classical SC series-parallel It essential from cost, volume, efficiency standpoint. threefold. highest depends output decreased as well, divided into two series-connected capacitors. presented results demonstrate operation with use branches, its switching strategies, stresses switches, efficiency, gain, regulation well zero-voltage (ZVS) operation. also issues related analytical loss modeling, extended concepts start-up, during transient states. demonstrated converter, discussion design, experimental setup clearly optimization achievements.
