Abstract

The invention is applicable to the technical field of power supplies, and provides a power supply control method and device and power equipment, and the power supply control method comprises the steps: carrying out the power supply control of the power equipment based on a plurality of continuous periods in a first power supply control mode, and starting a power supply circuit of the power equipment in a starting time period of each period, closing the power supply circuit in the closing time period of each period; wherein the time length of the starting time period in the next period is different from the time length of the starting time period in the previous period by a preset step length; and in the starting time period of any cycle, under the condition that the load current is detected, quitting the first power supply control mode, entering a second power supply control mode, and controlling a power supply circuit of the power supply equipment to be kept starting. According to the scheme, the situation of no-load misjudgment of the power supply equipment can be reduced, the power utilization requirements of various loads are met, the application range of the power supply equipment is expanded, and the effective utilization rate of the power supply equipment can be improved.

Description

technical field [0001] The present application belongs to the technical field of power supply, and in particular relates to a power supply control method, device and power supply equipment. Background technique [0002] A power supply is a device that stores electrical energy and supplies power to a load when needed. In order to enable the power supply device to detect the load and supply power at the first time after the load is connected, the traditional power supply device will keep the power supply circuit in the open state after the power supply is turned on, and when the power supply circuit is in the open state, the internal Switching semiconductors will inevitably generate switching losses, which will lead to unnecessary power loss when the power supply equipment is no-load, thereby reducing the power reserve and effective utilization of the power supply equipment. [0003] In order to reduce the power loss when the power supply device is not loaded, the traditional...
