Multiple‐terminal High‐voltage Hybrid Converters

Renewable energy sources, combined with energy storage systems and/or utility grids, can deliver continuous power to the loads. Thus, it is predicted that a hybrid converter is able to interconnect various energy sources and loads with fewer converter stages and higher energy efficiency. This chapter focuses on the configuration of the multiple‐terminal hybrid converter with single DC output. In order to construct a hybrid converter with both AC and DC inputs, the chapter explains the single‐phase six‐arm dual‐input single‐output AC‐DC converter. The feasibility of the proposed six‐arm hybrid converter will be proven by the simulation results. If the AC input voltage source of the hybrid converter is three‐phase, based on the nine arms AC‐DC converter, the nine‐arm hybrid converter with three‐phase AC input can be obtained by connecting one group of end points to three DC voltage source. The chapter illustrates the multiple‐arm hybrid converter with single‐phase and three‐phase AC input.
