Design of Boost Converter for High-Power DC Motor

Abstract
Design of Boost Converter for High-Power DC Motor
Jeong Hyeong Je

Graduate School, Gyeongsang National Univ.
Directed By Professor Hwi Beom Shin
In this paper, the design of interleaved boost converter for high-power DC motor is presented. The interleaved boost converter with transformer is composed of several identical boost converters connected in parallel. The converters are controlled by the interleaved switching signals, which have
the same switching frequency and the same phase shifting. By virtue of paralleling the converters, the input current can be shared, so that high reliability and efficiency in power electronic systems can be obtained. As aconsequence of the interleaving operation, the interleaved boost converter
with transformer exhibits both lower current ripple at the input side and lower voltage ripple at the output side. Therefore, the size and losses of the filtering stages can be reduced, and the switching and conduction losses as well as EMI levels can be significantly decreased.For the research, a formula of the interleaved boost converter with transformer is derived and differences of signal-phase boost converters. from the interleaved boost converter with transformer are considered. Also
a simulation of the interleaved boost converter with transformer is conducted. The program used in simulation is "Pspice". It premises general assumption that Each switching element is ideal element without loss.According to the terms desired, The boost converter keeps regular outputswithout ripple components.
