Abstract
The present disclosure presents a surge protection circuit, and a power supply device and an LED lighting device both applying the surge protection circuit. The surge protection circuit includes an inductive circuit and an energy-releasing circuit. The inductive circuit is coupled to a power loop for a load, and is configured to receive and temporarily store surge energy in the power loop. The energy-releasing circuit is connected in parallel with the inductive circuit, and is configured to release the surge energy for preventing the surge energy from affecting later-stage circuit(s).
