Document Type and Number:
WIPO Patent Application WO/2024/011416
Kind Code:
A1
Abstract:
A control method and apparatus for an electric heating appliance, and a controller and an electric heating appliance. The control method comprises: determining a first pulse width modulation signal, which can ensure stable on-off control over a first switch module (102), and loading same on a control end of the first switch module (102) to ensure stable on-off control in a state in which the first switch module (102) independently operates; then, acquiring a target operating parameter of a load (106) to determine at which duty cycle a second switch module (104) is to operate in order for the load (106) to operate stably according to the target operating parameter; and determining, on the basis of the first pulse width modulation signal and a second pulse width modulation signal, which are previously determined, a target pulse width modulation signal that meets both stable on-off control over the first switch module (102) and an output power requirement of the second switch module (104), and outputting the target pulse width modulation signal to the control end of the first switch module (102) such that the load operates according to the target operating parameter.
