Abstract
A switching control system, including: switch units, configured to separately receive one of alternating currents and couple to a load; a detection unit, configured to detect the alternating currents; and a control unit, configured to, after receiving a switching signal, and in response to detecting that a power supply alternating current and a backup alternating current are in a polarity half cycle and a voltage difference is less than a preset voltage, perform: closing a first turn-on direction of a power supply switch unit; opening a second turn-on direction of a backup switch unit; closing a second turn-on direction of the power supply switch unit; and opening a first turn-on direction of the backup switch unit; where the first turn-on direction is opposite to a direction of the polarity half cycle, and the second turn-on direction is the same as the direction of the polarity half cycle.
