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.

5. Module Description
5.1. Power Module
The 220V is connected by “ICN1” and “ICN2”. The 220V is rectified by “U4”, and supplied to
the pad. The “U11” is a 15V power module. It supply power to the MCU and IGBT driver.
5.2. IGBT Driver Module
The “START” is the system enable signal. When it is high, the system is enabled, else
disabled.
The “PPG-IGBT” is the IGBT drive signal. When it is high, the IGBT is opened, else closed.
The duty of the “PPG-IGBT” is to decide the pad heating power.
Page 12
12 / 18
Induction Heater C Library User Manual Version 1.2
MCU-AN-500087-E-12
5.3. Pad Driver Module
When the IGBT (U9) is opened, the current flow over the “PAD”. The “PAD” is a coil, so it will
save the power. The current direction is from left to right. Once the IGBT is closed, because
the “PAD” is a coil, the current direction is still from left to right. Because there is a C11, so it
and the “PAD” are made an oscillation loop, and the power will be saved in the C11. When
the system is working, if there is a cooker on the “PAD” coil, the cooker will be heated.

6.2. Operate Descript
Turn On/Off
When we have connect the power, the “Power” led will light. We can push the “Power” button
to turn on the device, and the “Power” led will start wink. At anything, we can push the
“Power” button to turn off the device.
Mode Change
When we turn on the device, the system is in standby. We must push the “M-Inc” or “M-Dec”
to start the system. The system has six work modes. You can push the “M-Inc” and “M-Dec”
to change the work mode.
Power Change
In normal, you can use the “Inc” or “Dec” button to change the power, and the range is from
200W to 2100W. When you change the power, the display will automatically change also.
Timer Set
At first, we push the “Timer”, the system will enter timer setting mode. We can push the “Inc”
or “Dec” to change the timer time. When we push the “Timer” again, the timer will be set and
started, and the “Timer” led will wink. If we want stop the timer, we must push the “Clear”.
Display Change
If you push the “View”, you will change the display information between power and time.
