Abstract:
1. A snubber circuit, comprising: a first capacitor, having a first terminal and a second terminal, wherein the first terminal of the first capacitor is electrically connected to a first terminal of the snubber circuit; a resistor, having a first terminal and a second terminal, wherein the first terminal of the resistor is electrically connected to the second terminal of the first capacitor; and a bipolar junction transistor (BJT), wherein one of an emitter and a collector of the BJT is electrically connected to the second terminal of the resistor, another of the emitter and the collector of the BJT is electrically connected to a second terminal of the snubber circuit, and a base and the emitter of the BJT are electrically conducted; wherein the snubber circuit further comprises a second capacitor, and the second capacitor is connected to the first terminal of the first capacitor and the second terminal of the resistor in parallel.
