摘要： A power supply includes a rectifying section for rectifying a sinusoidal a.c. voltage, a switching section for receiving a voltage output from the rectifying section, and a smoothing section having a smoothing capacitor. The power supply is controlled to have a sinusoidal load current and includes a power source circuit having a first path for conducting current from the rectifying section to the smoothing section and a second path for conducting current from an inductor of the switching section to the smoothing section, circuits for sensing the current flowing through the first path and forming a reference current with a target waveform based on the sensed current, circuits for sensing the current flowing through the switching element and determining a conduction ratio of the switching element to match the waveform of the sensed current to the waveform of the reference current, and a control circuit for sequentially controlling a plurality of switching elements connected in parallel based on the determined conduction ratio.

摘要： In a method and apparatus for controlling an air-conditioning apparatus of a type driving a compressor motor from a DC power source through an inverter, the present current value of a DC input to the inverter is detected, and, when the detected current value is larger than a current limit value, the rotation speed of the compressor motor is decreased by a predetermined value. The current limit is controlled so that it changes linearly relative to the rotation speed of the compressor motor.
