Abstract
For the Three-Input Integrated Dc-Dc (TIID) Converter, due to integrated structure and presence of common elements, each controlling input variable affects the three controlled output variables, and gives rise to interactions which make controlling difficult. Thus, to know the behavior of the converter and also to design the controller for three-input integrated dc-dc converter, it is necessary to quantify the interactions beforehand. This quantification helps to address pairing problem of integrated converter. Interactions of this integrated dc-dc converter are quantified using dc gain based and energy-based interaction measures. These are Relative Gain Array (RGA), Participation Matrix (PM), Hankel Interaction Index Array (HIIA), and H2 Norm-based Interaction Array (H2NIA). To quantify these interactions, a three-input dc-dc converter of 400 W, 24 V-30 V-36 V to 48 V is considered and the interactions are quantified in the MATLAB environment. The Hardware In Loop (HIL) environment of the OPAL RT simulator OP4510 is used to obtain the experimental results.
