摘要：
Based on the research of traditional single-stage step-up quasi Z source inverter, this paper proposes a TΓ hybrid single-stage step-up quasi Z source inverter (TΓ-qZSI) with a special impedance network structure, which is the combination of T type and Γ type impedance networks. The proposed circuit can achieve high voltage gain with small duty cycle and high modulation index. Besides, the design of turn ratio of coupled inductor is flexible and the input current is well distributed. This paper analyzes the operation modes of TΓ-qZSI and deduces the relationship of energy transformation between every parts of the circuit as well as the voltage gain. Finally, a 1000 W prototype was fabricated in the laboratory to do relative tests which verified the effectiveness and practicability of the proposed inverter as well as the correctness of theoretical analysis. © 2021, Solar Energy Periodical Office Co., Ltd.
