4.1 System 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. We can adjust the PWM width to adjust the
power. The fan is use to cool the IGBT. The feedback signal is used to protect the system
and calculate power. The feedback signal includes current, voltage, surge and temperature.

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 rises up to 300℃, the
system must stop work.
