扩展电流分流器带宽以实现宽禁带器件开关损耗的精确评估

Dominated by the zero formed by current shunt resistance and equivalent series inductance, the bandwidth of low-resistance current shunt is difficult to improve, which impedes accurate switching loss evaluation of latest wide-bandgap devices with higher current rating and faster switching speed. The article provides an unconventional Wheatstone-bridge viewpoint of the shunt model, revealing an “in...
