ABSTRACT:
An air conditioning system comprises an inverter that inverts commercial power into a variable-frequency AC and supplies it to a compressor; a DC power circuit for converting the commercial power into DC current; a unit for detecting an analog value of current supplied from the commercial power; and a control unit to control inverted digital data by compensating the digital current data discrepancy due to scattering of the DC control voltage, when there is A/D conversion after an actual power supplied to the inverter has been detected via the detector. The control unit comprises an A/D converter that uses the output of the DC current circuit as the reference for converting the current detection unit output into digital DC data, a controller that compares the allowable current data stored beforehand with the current data converted by the A/D converter and limits the output frequency of current inverted by the inverter so that commercial power current does not exceed the allowable value, a memory to store a compensated current value so that discrepancies in the current data can be compensated for on the basis of DC output discrepancies, and a compensator to compensate the current allowable value data.
