1. An abnormal current protection device, comprising:
an overcurrent protector, comprising:
a short-circuit detection unit, being configured to detect whether there is a short-circuit event within a period of debounce time of a protection cycle; and
an overcurrent detection unit, being configured to detect whether there is an overcurrent event after the period of debounce time within the protection cycle; and
a controller electrically connected with the overcurrent protector, being configured to disable a converter when the short-circuit event is detected, and disable a power stage when the overcurrent event is detected.
