1. PCB Power Supply : From the AC Input Voltage, it supplies DC 15V and 5V to the Inverter
circuit for the Compressor control.
2. COMP Driving / Feedback Circuit
It receives the COMP operation signals from the Main PBA and feedbacks the inverter errors
to the Main PBA.
3. Micom (MN103SFC2D)
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 (FNB40560)
