The invention provides a power supply protection circuit, device, system and method, and the power supply protection circuit enables a power supply to provide a power supply voltage for an energy storage circuit through the forward conduction of a switching circuit in a pulse low-level time; the energy storage circuit receives power supply voltage output by the power supply for energy storage; the switching circuit is reversely conducted within the pulse high-level time; and when the switching circuit is reversely conducted, the energy storage circuit outputs pulse voltage to the pulse load circuit to supply power to the pulse load circuit. According to the invention, the switching circuit is arranged to connect the energy storage circuit with the power supply and the pulse load circuit, and the switching circuit is switched on in a time division multiplexing mode, so that the use efficiency of the switching element is effectively improved and the resource waste is reduced in the process of using the energy storage element to supply power.
