Abstract

The analysis and control of Double-input integrated dc-dc converter is presented in this paper. The integrated converter is essentially a combination of buck and buckboost converters. However, on account of integration only one inductor is sufficient enough for performing the power conversion. In order to have simple control strategy as well as simpler compensator design a single loop control scheme, voltage-mode and current-limit control are proposed here for the power distribution. Closed-loop converter performance of this converter is simulated and compared with the theoretical predictions. The prototype of this converter is presented and the results are compared with simulink model.
