Title:
CURRENT FEEDBACK CIRCUIT AND ELECTRIC STOVE
Document Type and Number:
WIPO Patent Application WO/2024/092953
Kind Code:
A1
Abstract:
The present application relates to a current feedback circuit and an electric stove. The circuit comprises an electric stove arc striking circuit, a current feedback circuit and a processing module; a booster is connected between an output end of a switching power supply circuit and an input end of an ion needle assembly; the current feedback circuit is coupled to the output end of the switching power supply circuit; the current feedback circuit is configured to acquire a power supply signal of the output end of the switching power supply circuit to obtain a sampling signal; the processing module is respectively connected to the current feedback circuit and a control end of the switching power supply circuit, and the processing module is configured to receive the sampling signal and transmit a power supply adjusting signal to the control end of the switching power supply circuit according to the sampling signal, so that the switching power supply circuit adjusts the power supply amplitude of the power supply signal according to the power supply adjusting signal, thereby adjusting, in real time, the magnitude of the power supply signal output by the switching power supply circuit according to the numerical value of the sampling signal, to realize real-time feedback control according to a current. The overcurrent protection accuracy is improved, and the reliability of electric stove circuits is improved.
