摘要

In this paper, we propose a high-frequency switching pulse modulation utility-interfaced power conditioner with the flyback high-frequency transformer link and the switched-capacitor snubber cell. With the aid of the switched-capacitor resonant snubber cell, the high-frequency switching devices in the primary side of the proposed DC-to-AC power inverter can be turned-off with zero voltage soft-switching (ZVS). Moreover, the proposed power conditioner operates the currents in the discontinuous conduction mode (DCM) and takes the advantages of zero current soft-switching turn-on. Its output port is connected directly to the utility grid AC power source. At the end, the prototype of the proposed high-frequency utility-interfaced power conditioner (HF-UPC) is built and tested in the experiments. Its power conversion processing is verified and the output current is qualified in accordance with the guidelines of the power systems.
