Latest Patents

Chaur-Ping Cheng holds a patent for a "Three-phase power supply with three-phase three-level DC/DC converter." This invention includes a full-bridge thyristor converter with three sets of four in-series power switch elements, a three-phase isolated transformer, a full-bridge rectifier, a rectifying circuit, and a low-pass filtering circuit. The design is aimed at delivering power energy from the AC input voltage to the load efficiently. The power switch elements are controlled through a phase shift scheme, which allows for a three-level circuit structure that reduces the withstanding voltage of the power switch elements. Additionally, the zero-voltage switching (ZVS) is achieved by the isolated transformer and the power switch elements, further increasing the efficiency of the DC/DC converter.
