(R Room Inverter, LC4_3050)
1. PCB Power Supply: Supplies DC 15V and 5V to the Inverter circuit for the Compressor control.
2. COMP Driving / Feedback Circuit. It receives the R COMP(MSV) operating signals from the Main PBA and feeds the
inverter errors back to the Main PBA.
3. Micom (uPD78F1201)
4. BOOTSTRAP Charger: This is an independent power circuit for driving the IMP High-Phase IGBT.
5. Current Pickup Circuit: This picks up the currents taken by the Shunt resistance and performs the PWM DUTY control.
