Design and implementation of a digital controller for Multi-Input converter used in new energy combined power supply system

Abstract

Multi-Input converter has gained much more attentions because of the simplify circuit and less cost when implemented in the power system. As a new kind of digital control product, with lower costs, smaller package and higher level of integration, Digital signal controller (DSC), has a very good prospect in the field of digital control. Based on DSC TMS320F28035, this paper presents a new design and implementation for Multi-Input converter in order to realize the reasonable power distribution. All necessary DSC hardware or software techniques and algorithms required to implement the controller are discussed in detail. The steady state and dynamic response performance of the controller is presented in order to demonstrate the effectiveness of this design.
