In the system design, we will use some feedback signals to protect system or calculate
watt. The protect signal include over current, over voltage, surge voltage and kettle detect.
Anyone of them appears, the system must stop work. If the IGBT temperature is raise over
60℃, the fan must turn on. If the IGBT temperature is raise over 120℃, the system must stop
work. If the kettle is empty, the plate temp will raise. If the temp raise up to 300℃, the system
must stop work.

3. System Introduce
3.1. Hardware Block Diagram
The electromagnetic eddy current heating is our system theory. We use the PWM to control
the IGBT to generate the heating eddy current. The fan is use to cool the IGBT. The feedback
signal is used to protect the system and calculate power.
