Abstract

See full text

Disclosed is an electromagnetic heating control circuit, comprising a control chip, a rectifier filter circuit, a resonant capacitor, a switching transistor, a drive circuit, and a synchronous voltage detection circuit. The switching transistor comprises a first end, a second end, and a control end. The first end is connected to a positive output end of the rectifier filter circuit by using the resonant capacitor. The second end is connected to a negative output end of the rectifier filter circuit by using a current limiting resistor. The control chip comprises a positive phase voltage input end, a negative phase voltage input end, a voltage detection end, and a signal input end. The positive phase voltage input end and the negative phase voltage input end detect voltages at two ends of the resonant capacitor by using the synchronous voltage detection circuit. The signal output end is connected to the control end by using the drive circuit. The voltage detection end is connected to the positive output end of the rectifier filter circuit by using the synchronous voltage detection circuit. The control chip controls a working state of the switching transistor according to a voltage detected by the voltage detection end. Further disclosed is an electromagnetic heating device.
