| contents | Scalability and modularity are key features for future power converters, such that these systems can be easily employed in many applications with different electrical specifications. In this thesis, the potential of a new bidirectional phase-modular three-phase AC/DC converter with buck-boost capability is evaluated by means of studying two potential application cases and developing a hardware prototype for one of them. The DC-DC inverting buck-boost converter is a well-known and established topology. By connecting three such systems in parallel, a phase-modular bidirectional buck-boost DC-AC converter employing a minimum number of active components results, where for given AC voltage amplitudes, an arbitrary DC voltage can be generated and vice versa. Such a three-phase converter was not yet described in literature and this project aims at investigating the fundamental topology properties, as well as its performance limits. A hardware demonstrator is designed for one potential application in order to verify the basic operation and the expected high performance in terms of efficiency and power density. |
