IEEE Open Journal of the Industrial Electronics SocietyMetal oxide varistor (MOV) is a nonlinear resistive element whose resistance decreases rapidly when the applied voltage exceeds a threshold value. A dc solid-state circuit breaker (SSCB) uses MOVs or MOV with resistor-capacitor-diode (RCD) snubber ...

A Method for Optimizing Turn-Off Losses Design in Parallel MOSFETs Inverter with RC Snubber Circuits
EnergiesVoltage spikes are particularly severe in low-voltage high-current inverters due to the influence of parasitic inductance during the turn-off process. A resistor-capacitor (RC) snubber circuit is commonly connected in parallel with the switching device ...
