Working principle diagram of timer controlled microwave oven

Shown is the working principle diagram of a timer controlled microwave oven . High-voltage transformer, high-voltage rectifier diode, high-voltage capacitor and
magnetron are the main components of microwave oven.
    As can be seen from the circle, the main feature of this circuit is that the timer controls the power supply of the high-voltage transformer. After the timer timing knob is turned to a certain position
. The AC 220V voltage supplies power to the high-voltage transformer through the timer. When the predetermined time is reached, the timer returns to zero, the AC 220 V
power supply is cut off, and the microwave oven stops.
    The magnetron is the core component of a microwave oven . It is a device that generates high-power microwave signals. It can generate an ultra-high frequency signal of 2 450 MHZ when driven by high voltage
. Because its wavelength is relatively short, this signal is called a microwave signal. This microwave signal can be used to heat food.
