Abstract Conventional two-level Zeta converters have drawbacks, such as high voltage stresses and high current ripples. To address these problems, a three-level Zeta converter that uses a couple inductor is proposed in this study. The proposed converter utilizes the three-level power switching circuit to reduce the voltage stresses and inductor current ripples. Compared with the conventional converter, the proposed converter can improve power efficiency and power density. A 500 W prototype circuit is used to verify the operation and performance of the proposed converter via experimental results.
