Brief on Multiple Modules Series-Parallel Combined Inverter Systems

Abstract

Abstract:

In this paper, four kinds of series-parallel power conversion systems are introduced, in which multiple standardized inverter modules are connected in series or parallel at the output and input sides. The advantages of such systems include shortening the design process, reducing the cost, improving system reliability and so on. For these systems, the control objective is to achieve power balance among the modules and realize distributed and redundant control. Based on the existing reference, the control methods as well as the developing trend of these four kinds of systems are analyzed, discussed and summarized in the paper. It is also pointed out that for the IPOP inverter system the objectives of power balance and redundant control have both been actualized. While, for the other three kinds of inverter systems, the research still remain on the measures of power balancing and distributed and redundant control needs further study.

Key words: Inverter, combined system, current sharing, voltage sharing, distributed, redundant
