摘要

This paper presents a grid-interactive dual-paralleled buck/boost converter with four-quadrant power flow capability. The primary advantage of this topology compared to the traditional H-bridge inverter is its inherent robustness against shoot-through problems. Further, by combining the use of traditional Si devices with wide bandgap devices, one can get reduced power loss and higher power density at acceptable cost. This paper analyzes the operation modes of the converter under different conditions, and the control logic for the active switches to perform the four-quadrant operation of this converter is developed. Simulation results are provided to demonstrate the viability of the proposed approach.
