ENERGY CONVERSION DEVICE AND CONDITIONER USING THIS DEVICE Russian patent published in 2001 - IPC

FIELD: compressor driving conditioners organizing cooling cycle by means of energy conversion device. SUBSTANCE: device distinguished by its ability to approach harmonic to IEC standard has conversion section for rectifying and smoothing ac voltage applied to ac power supply and for ac-to-dc voltage conversion; inversion section for inverting rectified voltage to ac supply for load; inductance coil connected to side of conversion-section power supply; booster for shorting-out ac power supply through inductance coil and controller for setting shorting time by means of booster to optimize power factor of ac power supply in compliance with any of a number of differences between voltages of ac power supply, conversion section, and input power. EFFECT: increased power factor of power supply; improved harmonic approaching international standards. 18 cl, 20 dwg
