Function of main parts
NAME FUNCTION
INTELLIGENT POWER MODULE (IPM) It supplies three-phase AC power to compressor.
SMOOTHING CAPACITOR It stabilizes the DC voltage and supplies it to IPM.
CURRENT TRANSFORMER
It measures the current of the compressor motor.
It measures the current of the main power supply circuit.
REACTOR
It recti es AC, controls its voltage and improves the power factor of power
supply.
POWER FACTOR CORRECTION MODULE (PFC)
RESISTOR It restricts rush current with the resistance.
RELAY
It short-circuits the resistance which restricts rush current during the compres-
sor operates.
