Abstract

The invention relates to a device for controlling power supply. The device comprises a switch unit; a processor for controlling the on and off of the switch unit; and a capacitor unit for receiving electric energy for charging the capacitor unit from a power source when the switch unit is connected. When the load current provided for a load by the power source through the device is smaller than apreset first threshold value, the processor controls the switch unit to be disconnected with the power source; and the capacitor unit provides power for the processor during the switch unit disconnecting period, so that when the load is connected to the device, the processor can control the switch unit to be connected.

Description

technical field [0001] The present application relates to devices and methods for controlling power supply. Background technique [0002] For a long time, how to save energy has been a topic of concern to people. As we all know, if an electrical appliance is kept connected to a power source, the electrical appliance will consume power even if it is stopped, that is, the electrical appliance has no-load power consumption. Therefore, there is a need to provide an apparatus and method for controlling power supply that can reduce no-load power consumption. Contents of the invention [0003] In view of the above-mentioned problems in the prior art, on the one hand, the present application provides a device for controlling power supply, including: a switch unit; a processor, which controls the opening and closing of the switch unit; and a capacitor unit, When the switch unit is closed, it receives electric energy for charging it from the power source, wherein when the load cur...
