利用软开关电压变化率(dv/dt)整形技术抑制SiC驱动电机过电压

In silicon carbide (SiC) device based motor drives, the high-voltage slew-rate (dv/dt) associated with the fast-switching transitions results in excessive motor overvoltage, due to the reflected wave phenomenon, which increases the motor winding insulation stress and causes premature failure while raising electromagnetic interference (EMI) problems. This article proposes a soft-switching voltage s...
