摘要： An inverter control circuit of an air conditioner is provided to improve a power factor by reducing a phase difference between a current and a voltage of an input power and improving stability of the input power applied to a compressor motor by applying a charged current to a power factor compensation unit instead of a DC link unit. An inverter control circuit includes a converter unit, an inverter unit(70), and a power factor compensation unit(40). The converter unit includes a DC link unit(60) having a capacitor in order to convert AC power to DC power. The inverter unit inverts the DC power to AC power for operating a compressor motor(80). The power factor compensation unit is connected to an input terminal of the DC link unit in order to reduce a phase difference between voltage and current of input power applied to the compressor motor through the inverter unit.

摘要： An air conditioner having a power factor compensation function is provided to improve the performance and reliability of products by removing the harmonic component of a power source. An air conditioner having a power factor compensation function includes a power supply(10), a voltage waveform detector(20), a rectifier(40), a DC link part(60), and an inverter(70). The power supply receives three phased power source inputted. The voltage waveform detector detects a voltage waveform of the power source supplied from the power supply. The rectifier rectifies AC power source inputted. The DC link part smoothes the power source outputted from the rectifier and generates DC power source for driving a compressor. The inverter converts DC power source and supplies the compressor with the power source.
