When AC runs into noise filter P.C. board, its external noise is eliminated in NOISE FILTER CIRCUIT.
After noise being eliminated from AC, it is rectified to DC by REACTOR and PFC. If the operating frequency becomes 25 Hz or more, DC voltage rises to 370 V.
DC voltage, to which has AC been rectified by process 
, is stabilized by SMOOTHING CAPACITOR and supplied to IPM.
The DC (Bus voltage), which has been stabilized in process 
, is converted to 
CURRENT TRANSFORMER, which is placed in the power supply circuit to COMPRESSOR, are used to measure the val- ue of phase current and locate the polar direction of rotor with algorithm. PWM (Pulse width modulation) controls impressed voltage and frequency with those information.
