A second memory stores second PWM control signal pattern data being calculated in advance according to the harmonic removal pattern modulation system in the frequency region above the predetermined frequency for each of predetermined frequency intervals. A frequency designating section supplies frequency designating data. A controller reads out, when receiving the frequency designating data, either the first or second PWM control signal pattern data in accordance with the frequency designating data, from the first or second memory. An inverter outputs a predetermined AC power in accordance with the read-out first or second PWM control signal pattern data. An AC motor is variably speed driven in accordance with the frequency designating data, when receiving the predetermined AC power from the inverter.

摘要： This invention provides an inverter controlled air conditioner capable of employing a rush current preventing relay having a small capacitance, thereby decreasing the cost. An inverter circuit includes a rectifying circuit connected to an AC power supply, a smoothing capacitor connected to the output terminals of the rectifying circuit, and a switching circuit, connected to the two terminals of the capacitor, for outputting a voltage having a predetermined frequency upon performing switching. An auxiliary power supply circuit has a rectifying circuit connected to the AC power supply. A control section drives the switching circuit with an output from the rectifying circuit as the operation voltage. Relay drive circuits for receiving the output from the rectifying circuit as the operation voltage are connected to an electromagnetic contactor and a relay. When the air conditioner is started, the control section energizes the relay for a predetermined period of time t.sub.s through the relay drive circuits and thereafter energizes the electromagnetic contactor. Normally-open contacts of the electromagnetic contactor are connected between the AC power supply and the inverter circuit. The capacitor of the inverter circuit is connected to the output terminals of the rectifying circuit of the auxiliary power supply circuit through a resistor and normally-open contacts of the relay.

摘要： In an adjustable a.c. power supply for an air-conditioner system, comprising a first frequency converter for driving a compressor motor of a first air-conditioner, a second frequency converter for driving a compressor motor of a second air-conditioner, and a common a.c. power supply for delivering a.c. power to both frequency converters, a rectifier included in at least one frequency converter is constructed as a controllable rectifier and subjected to phase-control so that a synthetic higher harmonic current of the two frequency converters as viewed from the a.c. power supply is reduced. By conducting phase-control of plural controllable rectifiers in a manner that, e.g., one rectifier has a phase-control angle of zero degrees and the other rectifier has a phase-control angle of 30 degrees, load current from the a.c. power supply is permitted to have a waveform closer to a sine wave, i.e., a waveform in which higher harmonic components are further reduced.

摘要： A filter apparatus has a current-detecting coil. The coil detects a high-frequency leak current flowing from the phase-windings of a motor to the earth terminal through the closed case of a compressor. A current-canceling circuit generates a current similar in waveform to the high-frequency leak current detected by the coil. The current thus generated cancels out the high-frequency leak current.
