5-2. PBA Layout with part position (Inverter Board)
1. PCB Power Supply : From the AC Input Voltage(115V), 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)
