Buck-inverter converter for application in inductive wireless transmission

Abstract

This article presents the analysis and design of a Buck-Inverter converter, the proposed topology is based on the integration of two Buck converters, an inverter and a resonant load operating symmetrically. The control strategy for switching semiconductor devices simplifies the design of this topology. The converter and the control strategy proposed allow a sinusoidal output voltage waveform with minimum distortion, which is attractive for inductive wireless transmission. To validate the converter proposal an experimental prototype was designed at 15W, which was validated with simulation and experimental results.
