Abstract:
A power failure prevention system and method with a power management mechanism are provided. A switch circuit is connected to a first terminal of an inductor. An energy storage circuit is connected to the switch circuit. A pre-charged circuit is connected to an input power source and a second terminal of the inductor. A pre-charging control circuit is connected to the pre-charged circuit and configured to obtain a voltage of a node between the pre-charged circuit and the second terminal of the inductor, a voltage of the switch circuit or a voltage of the energy storage circuit as a pre-charged voltage. The input power source pre-charges the pre-charged circuit. When the pre-charging control circuit determines that the pre-charged voltage is higher than or equal to a reference voltage, the pre-charging control circuit controls the pre-charged circuit, allowing the input power source to charge the energy storage circuit.
