The processor 13 is configured to obtain a voltage requirement of the electronic device 1, and control a state of each first transformer circuit and a state of each second transformer circuit based on the voltage requirement.

In order to avoid starting a plurality of first transformation circuits with the same transformation parameters, the processor is used for controlling the state of each first transformation circuit and the state of each second transformation circuit in at least one first transformation circuit with different transformation parameters. In this way, the control of the processor can be made simple.

In the embodiment of the invention, because the battery protection board and the mainboard are respectively provided with the voltage transformation circuit, the processor can control the state of the first voltage transformation circuit on the battery protection board and the state of the second voltage transformation circuit on the mainboard according to the voltage requirement, so that the mainboard and the battery protection board can supply power to the load instead of only supplying power to the load through the voltage transformation circuit on the mainboard, and the phenomenon that the temperature of the mainboard is too high is avoided; in addition, the first voltage transformation circuit is arranged on the battery protection board, so that the structure of the main board circuit does not need to be changed, and the structure of the electronic equipment is simple.
