Document Type and Number:
WIPO Patent Application WO/2020/108509
Kind Code:
A1
Abstract:
A protection circuit(100) for ground short circuit protection, the circuit(100) comprising: a high conduction circuit(110) for controlling the supply of electric power for a functional circuit(1000), wherein the functional circuit(1000) has a boost function; and a charging subcircuit(120) for controlling, based on an input voltage of an input power source of the protection circuit(100) and an output voltage from the functional circuit(1000), the high conduction circuit(110) to be turned on or turned off; and an energy storage circuit(130) for storing electric power from the input power source so as to provide electric power for the functional circuit(1000).
