Abstract

A novel high-power modular input-series-input-parallel output-series connected DC/DC converter for medium-voltage application is proposed. Emphasis has been placed on power sharing control to compensate parameter mismatches and achieve equal power distribution between modules. Converter control is extended to achieve fault-tolerant operation by exploiting modularity to provide redundancy in the event of any failure. The proposed control scheme is validated through application-level simulations and scaled-down experiments to testify the reliability of the proposed control for ensuring power sharing between modules under a range of operating conditions. The results validate the proposed converter and associated control scheme indicating this to be a promising topology for high-power medium-voltage applications.
