Abstract
A snubber circuit includes: a capacitor including a first terminal and a second terminal, where the first terminal of the capacitor is electrically connected to a first terminal of the snubber circuit; and a Bipolar Junction Transistor (BJT), where one of the emitter and the collector of the BJT is electrically connected to the second terminal of the capacitor, and the other one of the emitter and the collector of the BJT is electrically connected to a second terminal of the snubber circuit. The snubber circuit can be electrically connected in parallel to an active component or a load to protect the circuitry connected to the load, and more particularly to absorb spike or noise generated during high-frequency switching of the active component to recycle energy, in order to achieve the goal of reducing spike voltages and enhancing efficiency.
