Abstract
We demonstrate the feasibility of radio-frequency (RF) communication based wireless load-sharing control of a two-module parallel dc-dc (Weinberg) converter unit (DDCU) operating at a high switching frequency (0.25 MHz). The impact of time delay (due to varying network sampling rates and channel disruptions) on the stability and performance of the DDCU are analyzed leading to robust control design, which compensates for the time-varying delays. Additionally, using experimental results, we demonstrate that an all-SiC (SiC VJFET and SiC Schottky diode) based hard-switched power-stage design achieves high efficiency in spite of operating at high frequency and high temperature.Keywords
