Abstract

This paper describes a novel approach to building a high efficiency and dimensionally compact power converter / inverter. A prototype was built for the Google / IEEE Little Box competition. The converter takes a 400-450 V DC input and creates a single-phase 230V AC output. It is capable of supplying 2kW continuously to a load. The design is based on a multi-winding DC-DC active transformer operating at around 500 kHz. The AC output sinewave is synthesized by switching between the DC tap levels produced by the active transformer. The transformer MOSFETs operate under ZVS and have an adiabatic gate driver. Early tests on the prototype demonstrate a high fidelity sinewave output and very high efficiency (better than 99%).
