Abstract

In this paper, the cost-effective design of an output reactor which is used to suppress the overvoltage at the motor terminal in an adjustable-speed drive (ASD) application is proposed. The overvoltage suppression mechanism of an output reactor in an ASD application is analyzed and the dominant parameters of the output reactor for the overvoltage suppression are extracted. Using these parameters as the design values and considering the high-frequency characteristics of the iron core in the reactor, a new cost-effective structure of the output reactor is proposed. Experimental results of the conventional reactor and the proposed reactor with a 15-kW induction motor are given to verify the proposed scheme
