Comparative analysis of an DC-DC interleaved converter of high power and control techniques

Abstract

This paper describes the methodology used to study the behavior of a DC-DC high power and high frequency interleaved converter, this converter can perform a comparative study of the frequency response resulting from each converter designed with different power parameters (between 10kW and 50kW), and a switching frequency of 20kHz. With the results obtained through the transfer function of each converter will be applied different control techniques, in order to determine the most suitable system for each controller. To comply the 'ideal' values determined by the different control strategies, or that the overall systems supports for proper operation. Finally, the power range for each control technique applied in the study is determined.
