WebMay 24, 2024 · 2 Answers Sorted by: 4 This snubber circuit is used to limit dv/dt during turn-off of the switch by presenting a higher load capacitance to the inductive load usually driven by the transistor. Without the snubber, the rate would be more or less only limited by the difference of load and switch current and the output capacitance of the switch. WebA resistor and a surge voltage suppression filter that can be arranged in a limited space such as the inside of a motor are provided. A resistor (21) used for a surge voltage suppressing filter is a strip-shaped resistor (21) in which lead wires (19, 19) are electrically connected to both ends of a conductive material having electrical resistance.
