A novel multi-inputs-single-output DC transformer topology

Nouri, Hassan; Al Zgool, Mais

Abstract

In this paper a novel Multi- Input-Single-Output (MISO) Boost Converter topology for renewable energy systems is proposed and presented. This pro- posed topology will be used to obtain different output voltage levels from several power sources, such as wind turbines, photovoltaic arrays, fuel cells, etc. Multi- Input Single-output converters provide flexibility in terms of the choice and the availability of power source, as well as enhancement in system reliability. The comprehensive operating principle, theoretical analysis and results are discussed in this paper.
The designed converter has the advantages of simple configuration, fewer components, high conversion ratio and high efficiency. Inputs and output are related mathematically in terms of L, C and the duty cycle of the IGBTs power switches. Also discussed is the derivation of the employed inductor L and the capacitor C in terms of size for a particular application.
The derived input and output expressions (for ideal and non-ideal converters) are solved numerically and the results are validated through PSCAD simulation.
