基于智能线圈的SiC驱动电机反射过电压抑制新方案

While wide bandgap (WBG) switches have revolutionized power electronics and motor-drive systems, the high $dv/dt$ associated with these fast-switching semiconductors can easily induce reflected high-frequency overvoltage spikes on motor stator terminals. The shorter rise time of the voltage pulses confines the cable length between the inverter and the motor in practice to avoid overvoltage across ...
