要約(英語): Demand for inverter air conditioners with superior energy conservation properties has recently increased globally. To promote inverter air conditioners, an electrolytic capacitor-less inverter is proposed that can meet the power supply harmonics regulations as a low-cost solution. This study presents motor current optimization technique based on the equations for an IPMSM and an electrolytic capacitor-less inverter, and the reduction of heavy rare earth. As a result, the motor peak current was reduced by 6.7% and the inductance of the AC input inductor was reduced, and the amount of heavy rare earth elements used in permanent magnet synchronous motors was decreased to less than 1/10th of that used in 1996.
