Description: Cooker detection control circuit. The control circuit is designed for testing cookers. The inductance coil disc lesion typically measures around 150 µH. The stove plate coil and capacitor resonate with device C203. When resonating, the voltage generated across C203 is relatively high, necessitating its specification as a high-voltage capacitor rated at 1200 V. An AC voltage of 22 V is rectified through a bridge rectifier to produce a DC voltage of 30 V, which is then applied to the stove hob coil, providing the necessary bias for the stove. Current flows through the stove plate coil, and upon reaching the gate control, the gate's operation results in the modulation of the coil currents, leading to the formation of high-frequency oscillations. These high-frequency oscillations enhance the heat generation efficiency of the cookers. The L and N terminals receive the 22 V AC input, and the varistor R201 serves a protective function by short-circuiting when the input voltage exceeds safe levels. Additionally, the circuit includes a fuse (FU) that will blow if the current exceeds safe limits, providing another layer of protection. Thus, the input section of the overvoltage protection circuit is equipped with both overvoltage and overcurrent protection devices.
The cooker detection control circuit operates by utilizing an inductance coil and a resonant capacitor to create a high-efficiency heating mechanism. The inductance coil, typically rated at 150 µH, is coupled with capacitor C203, which is rated for high voltage (1200 V) to withstand the resonant voltage during operation. The circuit begins with an AC input of 22 V, which is converted to DC using a bridge rectifier. The resulting DC voltage of 30 V is applied to the stove hob coil, which generates a magnetic field necessary for induction heating.
The interaction between the stove plate coil and the gate control mechanism is crucial for regulating the current flow. When the gate control is activated, it allows current to pass through the coil, generating high-frequency oscillations. These oscillations increase the efficiency of heat generation, making the cookers more effective in cooking applications.
Protection features are integrated into the circuit design to ensure safe operation. The varistor R201 is a voltage-dependent resistor that acts as a protective device, short-circuiting when the input voltage rises above a predetermined threshold, thus preventing damage to the circuit components. The inclusion of a fuse (FU) further enhances safety by disconnecting the circuit in case of excessive current, thereby protecting against potential hazards.
Overall, the cooker detection control circuit exemplifies a well-designed system that combines efficient heating technology with robust safety measures, making it suitable for modern cooking applications.Cookers detection control circuit The control circuit shown in cookers for testing.

Current flows through the coil plate stove, the mutual inductance transformer after arrival gate Control. Control of the gate is turned off will make the disc lesion in the coil currents pass, off the change, the formation of high-frequency oscillations.
High-frequency oscillations of current to the heat generating efficiency cookers improved. L, N terminal then two 22V AC input, the loop voltage protection varistors R201 play the role, that is, when the input voltage is too high, the varistor R201 will play a short-circuit protection. In the circuit also has a fuse FU. When the machine current is too large, FU will fuse, which is a means of protection. Therefore, the input into the overvoltage protection circuit portion is usually provided a device and a overcurrent protection devices.
