摘要
In order to further improve the voltage gain of the traditional Y-source inverter, a series output type high-gain impedance source inverter topology is proposed. The topology is a two-stage circuit. The front-stage circuit is composed of two symmetrically designed switches in front of an improved Y-source DC-DC topology, which optimizes the switch stress and expands the duty cycle adjustment range; the second-stage circuit is full Bridge inverter circuit. Through the symmetrical design of the pre-stage circuit, a higher DC bus voltage is obtained by connecting the outputs in series. To further improve the power density, the planar magnetic components and SiC switches are adopted. Establish a theoretical model of planar inductance, analyze the advantages and disadvantages of different winding arrangements, and determine the inductance parameters with the help of finite element simulation software. In order to verify the theoretical analysis, an experimental platform is built, and a Y-source coupled planar inductor is designed and manufactured. The experimental results show that: under the rated power, the boost ratio can reach 5, which effectively improves the voltage gain.
