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.
