3 System Level Architecture of the Board

3.1 Board Block Diagram Figure 3-1 gives a system level architecture of the demo board. It has these sections: control, power supply, resonant circuit.

Figure 3-1: Board Block Diagram


MCU-AN- 500086-E-12 –

3.2 Control Module The Control Module is based on the MB95F430H. It has several specialized hardware peripherals, like 16-bit output compare unit, 10-bit ADCs, internal voltage comparator, OPAMP and buzzer driver, which are required for inductor heater control.

3.2.1 MCU Socket The demo board uses a LQFP32 footprint for MB95F430. Additionally, there is a test pin for each pin of MCU.

3.2.2 Key and Display There are 8 single LEDs (D1-D8) and a LED module on the front board. The LEDs indicate the mode that the inductor heater is being in. The LED module displays the output power Level in constant power mode, temperature in constant temperature mode or time in timing mode.

All the keys are capacitive touch sense buttons. This function is implemented through AT5088 which is an ASIP for capacitive touch application. The AT5088 can support 8 buttons max.

Figure 3-2 shows the key and display definition

Figure 3-2: Key Definition The front board is connected with the main board through the 10-pin port including 5 wires for LED COMs, 2 wires for I2C bus and 2 wires for GND and +5V. The socket J2 on the front board is prepared for AT5088 tuning.

Figure 3-3 shows the connector.

3.2.3 Fan and Buzzer When the inductor heater works, the fan need to work at the same time to chill the heat-sink, and decrease the temperature of the rectifier module and IGBTs in advance. The fan is a 12v driving set. A 7812 is used to convert the 15v to 12v.

The buzzer module is located on the main board, and it is drove by the specialized BUZ pin of the MCU.

3.2.4 Temperature Measure Circuit In order to avoid the IGBT failure caused by over temperature, a NTC is placed on the top of IGBT Q1 to monitor the temperature.

Apart from the NTC on IGBT, there is another NTC is used to measure the temperature of the pot. It is placed in the middle of the wire plate where is close to the bottom of the pot.

Pin 1


MCU-AN- 500086-E-12 –

Figure 3-4: Temperature Measuring Port

3.2.5 Debugger Interface Socket J1 on the main board provides an interface for BGMA with MCU. The user can program the MCU or do debugging using the BGMA.

3.2.6 Pot detect circuit Before the heater begin working, make sure there have a pot on the heater winding, otherwise, the heater can’t start-up. Therefore, the heater need to judge there have a pot on it or not. The pot is detected by the numbers of pulse which the MCU counter count according to the output of a comparator integrated in MCU.

Figure 3-3 shows the elements

Figure 3-5: Elements of Pot Detection

3.2.7 Phase Lock and Frequency Tracking Control circuit The frequency tracing circuit is designed with phase-locked-loop MCU of CD4046, using phase comparator II. If the signal-input lags the comparator input in phase, the output is low level, if the comparator input lags the signal in phase, the output is maintained high level. So, according to the output level of the CD4046, we can know what area where the switching frequency is lower than the resonance frequency or higher than the resonance frequency the heater worked.

IGBT temperature measure

Plate temperature measure


MCU-AN- 500086-E-12 –

When the output of the CD4046 is low level, we can adjust the power at each state until the output of the CD4046 is high level, and then, the output power of the heater arrive at the maximum power.

Figure 3-6: Elements of Phase lock

3.3 Power Supply

3.3.1 SMPS A +15v DC block power supply (U1) serves as the main power supply to the control section of the demo board. The +15v power supply is supplied to the gate driver directly. A +12v power supply for the fan is generated using a regulator (U3). The +5v is also generated from +15V using the regulator U2.

3.3.2 Filter and Rectifier Before entering into the resonant sink, the 50HZ AC power has to be change to DC-Link by the Filter and Rectifier stage. The filter part consists of some protection components, induction and capacitors, such as fuse (F1), relay (RL1), inductor (L2), and capacitor (C16, C14, and C21). Rectifier module RL1 convert AC to DC, then the DC power go through the L1 and C22 to the resonant sink. A current transformer T2 is embedded in the circuit for AC current measure. For more information please refer to the chapter “Schematic and BOM”.


MCU-AN- 500086-E-12 –

3.4 Resonant Circuit

3.4.1 IGBT driver The IGBT driver circuit is built around IR2113 manufactured by IR. There are two power supplies for it. One is +15v which will supply power to the IGBT gate, and another is +5v which supply power to the logical part of the component.

JMP1 is used to disable or enable the driver output. When the jumper is open, the driver output will be enabled, or it will be disabled.

Figure 3-7: IGBT Driver Block

3.4.2 Resonant Tank IGBT Q1 and Q2, C18, C24 and wire plate make up the main part of the resonant tank. J8 and J9 sever as the headers for wire plate connection. Current transformer T1 is added to the resonant sink serial with the wire plate. It will transform the current to the MCU for over current protection. A heat-sink is used here to disperse the heat generated by IGBTs and rectifier.
