전기에너지를 기계에너지로 변환하는 기존의 브러시 있는 직류모터보다 고효율, 저소음, 제어용이성, 고내구성 특징을 가지는 브러시 없는 직류(BLDC: Bipolar CMOS DMOS)모터의 응용분야의 확대로 지속적으로 성장하는 BLDC 모터시장에 대응하기 위한 에너지 절감형 BLDC 모터구동시스템 기술개발이 절실히 요구되는 실정이다. 이에 따라, 본고에서는 일반차량 및 PHEV(Plug-in Hybrid Electric Vehicle)/EV(Electric Vehicle) 등 그린자동차용, 에어컨, 세탁기, 냉장고 등 그린백색 가전용, 산업용 건조기, ATM, 자판기 등 그린산업 기기용 BLDC 모터에 적용할 수 있는 에너지 절감기능이 우수한 BLDC 모터, BLDC 모터구동회로, 고전압 파워소자구동회로, 고전압 파워소자로 구성된 BLDC 모터구동시스템 기술동향에 대해 논의하고자 한다.
