5-2) Parts Layout (Inverter Board)
1. PCB Power Supply : Circuit changing the input power to the fridge control power with SMPS.
After converting to 12V and 5V, supply them to Main PBA.
After converting to 15V and 5V, use them for Inverter control.
2. Bootstrap Circuit : Independent Power Circuit for IPM High-Phase Driving.
3. Location Pick-Up Circuit : Detection of Rotor Location by monitoring the U/V/W-Phase of Compressor.
4. IPM : It is a Power Module which consists of HVIC(1), LVIC(1), IGBT(6) and Diode(6) and drives the
compressor with IGBT On/Off controlling at the Micom.
5. Shunt Resistor : Compressor Current Detection Circuit. It protects the compressor from over-currents by
monitoring the voltage applied to the related resistance.
