一种功率半导体器件的变换器级通态电压测量方法

This letter proposes a converter-level method for measuring the on-state voltages of all power semiconductors in a single-phase inverter by using a single circuit only. The proposed circuit distinguishes itself by connecting to the middle point of each phase leg, instead of the two power terminals of individual devices as conventional methods do. It has the advantages of reduced circuit complexity...
