Title:
POWER SUPPLY CONTROL SYSTEM AND POWER SUPPLY CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/208217
Kind Code:
A1
Abstract:
The present invention provides a power supply control system. An internal electronic switch is turned off to control a null line time-sharing generator to be directly electrically connected, and a null line is electrically connected to a null line end of an intelligent switch by means of the null line time-sharing generator, so that null-live-line power supply of the intelligent switch is achieved. The internal electronic switch controls, in a closed loop, a live line time-sharing conduction device to be turned on to supply power to a load device in a time-sharing mode, and according to the set time corresponding to one-time of multi-time cut-offs at zero-crossing points of an alternating-current sine wave, the null line time-sharing generator is automatically cut off when detecting that the live line time-sharing conduction device is turned on; when the null line time-sharing generator detects that the live line time-sharing conduction device is cut off, the null line time-sharing generator is automatically turned on to make the null line electrically connected, thus supplying power to the intelligent switch in the time-sharing mode, so that null-live-line power supply of the intelligent switch is achieved. The present invention provides a power supply control method. By adopting the technical solution of the present invention, the null-live-line power supply of the intelligent switch is solved under the condition that a switch cassette box has no null line, the installation is easy, and an application range is wide.
