Abstract
Along with the development of the control technology of PMSM motor, reliability, life time and power density have become important issues. The electrolytic capacitorless AC motor drive with three-phase power supply holds advantages of small volume, long service time and high reliability, which is an important development direction of motor drives. Currently, electrolytic capacitorless AC motor drives are already applied in industry. Based on the stable operation of the drive and the performance control technology of the machine side, the development status of the electrolytic capacitorless AC motor drive is summarized and the advantages and disadvantages of the existing schemes are pointed out. Finally, the current difficult problems and future development trend of the electrolytic capacitorless AC motor drive are summarized and prospected.
