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.
