串联SiC MOSFET有源钳位拓扑分析及灵活DV/DT控制

Series-connection of SiC mosfets is an attractive solution to build cost effective and high efficiency medium voltage converters, however, the unequal voltage sharing among the power devices and the induced high dv/dt problems should be considered carefully. In this article, an active clamping topology and corresponding dv/dt control method for series-connected SiC mosfets are proposed. With the p...
