要約(英語): Large-capacity air conditioners are widely used in office buildings, schools, hospitals, and so forth. Downsized and energy-efficient large-capacity air conditioners are strongly required in such applications. This paper proposes a new low-loss boost-chopper circuit, which is applicable in large-capacity air conditioners. The basic principle of the proposed low-loss boost chopper is discussed in detail. Experimental results of the proposed boost chopper demonstrate that the conversion efficiency is improved, achieving a stable boost operation of dc-bus voltage. A new compressor motor is also proposed considering the stable boost operation of the dc-bus voltage. It is also demonstrated that the total conversion efficiency between an ac-side input terminal and an output terminal of an inverter including a diode rectifier and the proposed low-loss boost-chopper circuit with the newly proposed compressor motor is improved. This improved efficiency of inverter system contributes to reduce the installation area and weight of the newly developed model by 50% and 31%, respectively, as compared to those of the previous model.
