Title:
POWER CONTROL CIRCUIT AND POWER CONTROL METHOD FOR ELECTROMAGNETIC HEATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/109916
Kind Code:
A1
Abstract:
The present application discloses a power control circuit and a power control method for an electromagnetic heating device. The power control circuit comprises: a resonant circuit; a control circuit, connected to the resonant circuit and configured to control the resonant circuit to work on the basis of a power control signal; and a detection circuit, connected to a resonant loop of the resonant circuit, connected to the control circuit, and configured to detect an output power of the resonant loop. The control circuit is further configured to adjust the power control signal on the basis of the output power and a target power of the resonant circuit, so as to control the resonant circuit to work by using the adjusted power control signal. In this way, the power control accuracy of the electromagnetic heating device can be improved.
