Abstract:
An electromagnetically heated cooking utensil, and a heating control circuit and method therefor. The heating control circuit includes a first resonance device; a second resonance device; a first power switch; a second power switch; a first synchronization device that detects voltages of both ends of the first resonance device to output a first synchronization signal; a second synchronization device that detects voltages of both ends of the second resonance device to output a second synchronization signal; and a control device that selects, according to the heating mode of the electromagnetically heated cooking utensil, the first synchronization signal to generate a driving signal for driving the first power switch, a second synchronization signal to generate a driving signal for driving the second power switch.
