Fig. 1 is a flowchart of a heating power control method of an electromagnetic heating system according to an embodiment of the present invention. As shown in fig. 1, the heating power control method of the electromagnetic heating system includes the following steps:
and S1, acquiring the target power of the electromagnetic heating system and continuously detecting the feedback power of the electromagnetic heating system.
