Embodiment 1

[0042] Such as figure 1 As shown, in the embodiment of the first aspect of the present invention, a power supply control device 100 is provided, including: a power supply circuit 102; a delay start circuit 108, an input terminal of the delay start circuit 108 and an output terminal of the power supply circuit 102 connected, the delay start circuit 108 includes an energy storage device C; the controller 110 is connected with the acquisition end of the delay start circuit 108 and the control end of the power supply circuit 102, and the controller 110 is configured to cut off the power supply circuit 102 according to the corresponding The electric signal is used to obtain the discharge voltage value of the energy storage device C; and the first duration is determined according to the discharge voltage value, and the power supply circuit 102 is controlled to resume power supply according to the first duration.

[0043] In one embodiment of the present invention, the controller 110...

Embodiment 2

[0055] In one embodiment of the present invention, the power supply control device 100 provided by the present invention is described by taking the application scenario of an inverter compressor of a refrigerator as an example:

[0056] In related technologies, for refrigeration equipment with variable frequency compressors, in terms of control technology, it is difficult to control the heavy load start-up of variable frequency compressors, especially when power is turned on again after a sudden power failure. At this time, the suction and exhaust pressure of the system is unbalanced. It is more likely to cause startup failure under these conditions. In order to deal with the problem that the compressor fails to start due to sudden power failure and power on again, some solutions are to set the delay start time in the main control chip software, and wait for a fixed period of time before starting the compressor every time the power is turned on. In this way, the start-up time ...

Embodiment 3

[0065] Such as image 3 As shown, in one embodiment of the present invention, a power supply control method is provided for controlling the power supply control device provided in any of the above embodiments, the control method includes:

[0066] Step S302, obtaining a power-off signal corresponding to the power supply circuit, and obtaining a discharge voltage value of the energy storage device according to the power-off signal;

[0067] Step S304, determining the first duration according to the discharge voltage value, and controlling the power supply circuit to resume power supply according to the first duration.

[0068] In one embodiment of the present invention, as Figure 4 As shown, the steps of controlling the power supply circuit to restore power according to the first duration include:

[0069] Step S402, acquiring a preset duration;

[0070] Step S404, based on the fact that the first duration is longer than the preset duration, control the power supply circuit...
