A Three-Port High-Gain DC-DC Y-Source Converter for Renewable Energy Power Generation System

This paper proposes an improved three-port high-gain DC-DC Y-source converter, which can be operated in five Modes. By introducing the Y-impedance source network, a higher voltage gain and greater design flexibility can be realized. In addition, the current of each port is continuous, which is suitable for the application of renewable energy power generation systems.
