snubber circuit

In switching power supply circuits, this is a circuit used to suppress noise such as ringing by absorbing it. There are RC snubber circuits consisting of a resistor and a capacitor, as well as RCD snubber circuits with an added diode. While snubber circuits offer the benefit of suppressing noise, they also have the drawback of increased circuit loss, leading to reduced efficiency. Therefore, snubber circuits need to be designed to suppress noise while minimizing losses.
