Abstract

This invention disclosure is going to present a phase-shift DC/DC converter with a commonmode (CM) voltage reduction modulation. The proposed technology has the following merits: 1. The CM voltage is reduced close to zero. 2. The reduction in CM voltage can significantly reduce CM current, resulting in smaller CM filter and cost saving, as well as efficiency and power density improvement. 3. The reduction in CM voltage can also help in high-frequency (HF) transformer design in terms of parasitic capacitance and inductance optimization.
