Resistor-Capacitor (RC) Snubber Design for Power Switches

WebMar 28, 2015 · Its resistance value and its power rating must be deduced from the worst-case conditions for both scenarios. The power rating is also related to how frequently the switch is going to be operating. Note that at the instant the switch opens, the capacitor is discharged and the load current is driven through the resistor, so its value must be low … WebQuick Snubber De sign: Where power dissipation is not critical, there is a quick way to design a snubber. Plan on using a 2-watt carbon composition resistor. Choose the resistor value so that the same current can continue to flow without voltage overshoot after the switch opens and the current is diverted into the snubber.
