Equipment control method and device, equipment and storage medium

The invention relates to the technical field of electrical engineering, in particular to an equipment control method and device, equipment and a storage medium. The method comprises the following steps: acquiring electrical parameters of equipment; calculating turn-on loss and turn-off loss of the switch tube according to the electrical parameters, and determining the surface temperature of the switch tube based on the turn-on loss and the turn-off loss; whether the surface temperature is larger than a preset temperature threshold value or not is judged; if yes, the current carrier frequency of the equipment is extracted from the electrical parameters, a second carrier frequency is determined based on the surface temperature, the current carrier frequency and the temperature threshold value, and the second carrier frequency is the carrier frequency corresponding to the next moment of the current moment; controlling the equipment according to the second carrier frequency; therefore, the problem that in the pri
