Title:
POWER SUPPLY SWITCHING METHOD AND DEVICE, AND HAND-HELD TERMINAL
Document Type and Number:
WIPO Patent Application WO/2015/131586
Kind Code:
A1
Abstract:
A method and a device for power supply switching, and a hand-held terminal. The device comprises: a detection circuit (28) electrically connected between a main power source and a bidirectional switching circuit (26); the bidirectional switching circuit is connected between a back-up power source and a load; the detection circuit is configured to detect the working state of the power supply circuit of the main power source and to produce a first control signal when said working state is normal; the bidirectional switching circuit receives the first signal and opens a first circuit connection between the power supply circuit (22) of the main power source and the power supply circuit (24) of the back-up power source, and closes a second circuit connection between the power supply circuit of the back-up power source and the load.
