Induction Cooker Electrical Control Part Of The Design

The project studied by this thesis is the electrical control design of induction cooker. This thesis introduces the development course, working principle, function realizing principle, hardware circuit design principle as well as MCU program's structure of induction cooker. The designed induction cooker has advantages like low cost, many interface, complete function etc. there is certain some market competition ability.Hardware circuit includes the unit loop circuits such as main loop circuit, drive circuit, control circuit, protective circuit, the circuit of power source and displaying circuit etc. The function that the induction cooker can realizes are mainly as follows: heat function, warm function, time function, no pan detecting and alarm function, which includes overheat alarm, over voltage or under voltage alarm, fan failure alarm etc. The displaying interface has Digital Number Display Indicator and Vacuum Fluorescent Display. The use of MCU makes the induction cooker intelligence, mainly offers good man-machine interface, power automatic control and temperature automatic control, time control as well as various automatic detections alarm etc. This system covers many fields such as electronics, mechanicals, magnetic, algorithms etc. MCU program structure divides into two parts as main program and timer interrupt service program, after many times' testing and running, the program runs steadily and reliably.
