6-2) Connector Layout & Descriptions of Inverter Controller Board
1. PCB Power Supply : From the SMPS circuit, it supplies 15V and 5V for the Main PBA control and
supplies15V and 5V to the Inverter circuit for the Compressor control.
2. Inverter Control Circuit : Fridge Compressor Control Circuit.
3. COMP Driving / Feedback CircuitIt receives the COMP operation signals from the Main PBA and
feedbacks the inverter errors to the Main PBA.
4. BOOTSTRAP Charger : It is an independent power circuit for the driving of the IMP High-Phase IGBT.
5. Current Pickup Circuit : It pickups the currents taken by the Shunt resistance and does the PWM DUTY
control.
6. IPM (FNE41060)
7. Micom (MN103SFC2D)
