4-3-2. Power Source (HYBRID IC)
1) The power supplied by Noise-Filter is rectified through COMP OLP and the voltage of 300V/DC, rectified
through DIODE, is applied in parallel to the SPM and SMPS area, a compressor operating driver.
2) The power source is the circuit which reduces 300V/DC to each 12V/DC and 15V/DC by Hybrid IC, and
supplied to operate the MICOM for controlling COMP, and SPM.

4-3-1. INRUSH CURRENT Protecting Circuit
1) The Power Thermistor prevents an instant inrush of current generated in condenser(C1) when plug in, and
Relay(K1) operates 0.1 second after plug in and the power is supplied by relay afterward.
2) The Fuse 1 is designed as 5A to prevent over current applied to Compressor, and Fuse 2 is designed as 1A to
protect SMPS area and power in secondary part.
