Abstract :
Problems involving long cable PWM motor drive systems are well documented in the literature. Solutions based on passive filters are conventionally used to suppress the undesired high-frequency phenomena that take place in such systems, but, in turn, bring up new considerations concerning filter size, weight, cost and electrical losses. In this context, an alternative concept of a motor drive system that overcome all these problems is outlined in this paper, where the long cable is used to connect the rectifier to the inverter, thus establishing a DC power transmission link. This paper briefly discusses the benefits and important issues concerning the proposed system and presents a comprehensive analysis regarding one of its advantages, which is the copper (and cost) economy in relation to the traditional systems.
