A Methodology for Even Power Sharing among Input Sources in a Multiple-Input DC-DC Converter Topology

Shailesh Kumar Nag | Anjanee Kumar

Abstract: Among the power electronic converters, dc-dc converters find applications in key areas such as dc drives, battery charging, electric traction, renewable power generation and so on. While many topologies of dc-dc converters are popular, multiple input converters (MICs) have been emerging as practical and efficient means especially for hybrid energy systems. In this paper, a methodology is presented to extract equal powers from multiple (either symmetric or asymmetric) input dc sources of an MIC. The algorithm works on the principle of varying the duty ratios of switches to regulate the average current drawn from each source. Mathematical formulations are presented to describe the scheme. In addition, software based simulation results are presented to validate the proposed methodology.
