1. PBA Power Supply : Supplies DC 16V and 5V to the Inverter circuit for the Compressor control.
2. COMP Driving / Feedback Circuit
It receives the COMP(MSV) operation signals from the Main PBA and feedbacks the inverter errors to the Main PBA.
3. Micom (uPD78F1201)
4. BOOTSTRAP Charger : It is an independent power circuit for the driving of the IPM High-Phase IGBT.
5. Current Sensing Circuit : It pickups the currents taken by the Shunt resistance and does the PWM DUTY control.
6. IPM (IGCM04G60HA)
5-2) Parts Layout (Inverter Board)
