Claim 19:
20. The dummy load control method according to claim 19, wherein the dummy load module has a dummy load control end, wherein a constant voltage source provides a constant voltage to the dummy load control end, the dummy load control circuit comprises a first switch and a second switch, the first turn-on voltage is a threshold turn-on voltage of the first switch, and the dummy load module is turned on when the first switch and the second switch are turned off, and is turned off when the first switch and/or the second switch are turned on, wherein
the dummy load control method further comprises:
controlling the second switch by using the input voltage of the power supply input end, so that the second switch is turned on when the input voltage is greater than the first power supply voltage, and is turned off when the input voltage is less than the first power supply voltage.
