High Gain DC/DC Converter Topology With Switching Capacitor

Two kinds of high-gain DC/DC topologies with switching capacitors are analyzed. In order to improve the input ripple, the structure of the two converters is optimized and expanded on the basis of the original topology, which effectively improves the input current ripple, improves the stability of the input power supply, reduces the voltage stress of the device, and achieves higher voltage gain under the same duty cycle. Therefore, the improved topology is ideal for places with special requirements for input current ripple and high output voltage. Finally, the correctness of the topological structure is verified by setting up an experimental platform.
