Control method for driving frequency of resonant converter, power supply module and electric equipment

The invention provides a control method for the driving frequency of a resonant converter, a power supply module and electric equipment. The method comprises the following steps: acquiring instruction demand information and detection information detected by a detection unit; according to the current environment temperature, whether the driving frequency of the first resonant converter is adjusted or not is determined, and if yes, the initial driving frequency of the first resonant converter is increased to the target driving frequency, and the initial driving frequency of the second resonant converter is decreased to the actual driving frequency in the current control period; when the temperature of the second resonant converter meets a first preset condition, lowering the target driving frequency of the first resonant converter to the initial driving frequency, and raising the initial driving frequency of the second resonant converter to the target driving frequency; and when the temperature of the first res
