Abstract
In a power converter specified to convert from wide-range and high-level DC voltage or AC line voltage to low-level DC voltage, satisfying high efficiency, high power density, and high power factor is challenging because of the higher device stress and difficulty of maintaining ZVS/ZCS conditions. Our purpose of the proposed two-stage power conversion architecture is to manage this high peak voltage stress and widely-varying operating conditions and to reduce dissipation by placing a switched capacitor pre-regulator stage in front of a very high frequency DC-DC converter stage. Our proposed two-stage architecture has been designed, built, and tested.
