A simple cuk converter derivated two-quadrant DC motor controller

Abstract

DC drives are still very important especially for low voltages and low power (e.g. in cars and robots). In this paper a Cuk-derived (one- and two-quadrant) converter is analyzed which makes it possible to control the voltage across the machine (and therefore the speed) from zero to three times of the input voltage. The model of the drive, the design of the devices, and some experimental results are given.
