Power supply control method and device, control terminal and storage medium

The invention provides a power supply control method and device, a control terminal and a storage medium. The control method comprises the steps that when a power supply shutdown instruction is detected, the voltage of a direct-current bus is acquired; and if the voltage of the DC bus is greater than the preset voltage, the duty ratio conduction between the input end of the DC conversion module and the output end of the DC conversion module is controlled to form a discharge path. According to the invention, when the power supply is shut down, the DC conversion module drive is turned off, and the DC bus is overvoltage, the duty ratio between the input and the output of the DC conversion module is switched on to form a discharge loop, thereby avoiding the overvoltage of the DC bus and the equipment fault caused by the fact that the energy of the rectification module cannot be released, and effectively improving the safety and stability of the power supply. 本发明提供一种电源的控制方法、装置、控制终端及存储介质。该控制方法包括：当检测到电源关机指令时，获取直流母线的
