"This document can not be used without Samsung's authorization" 7. PCB Diagram To do list "This document can not be used without Samsung's authorization" 7-2. 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. 6. IPM (FNE41060) 7. Micom (MN103SFC2D) "This document can not be used without Samsung's authorization"
