A discrete time domain controller design to a Three-Phase Step-UP DC-DC converter with a three-phase high frequency transformer

Abstract

This paper presents a discrete controller design approach applied in a three-phase step-up DC-DC converter with isolated high frequency transformer. In addition it presents the topology and the step up converter working at region R2. The compensators at the continuous and discrete time domain are designed based on the root locus method. In the same way by means of simulation results, this work presents a comparative analysis with the both domains design to the current and voltage loops. The experimental implementation of the discrete controller using the DSC 56F8323 is under development.
