IPDU_(TM) Inverter Devices for DC Brush less Motors

摘要

Toshiba Carrier Corp. has developed IPDU_(TM) (Intelligent Power Drive Unit) inverter devices to realize energy saving for DC brushless compressor motors. The IPDU_(TM) features original high power factor control technology conforming to the International Electrotechnical Commission (IEC) specifications.This paper describes IPDU_(TM) inverter devices for DC brushless motors, as well as compressor efficiency improvement by advanced vector motor control. Furthermore, the IPDU_(TM) based on the inverter for air conditioners can be applied not only to compressor drives, but also to DC brushless motor drives in various industries.
