RealTime emulation of a three-phase vienna rectifier with unity power factor operations

In this paper a FPGA-based dynamic model of a three-phase Vienna Rectifier with unity power factor operations has been developed addressing applications as stationary chargers for electric vehicle or telecom rectifiers. Such a model has been implemented to be used in a Hardware In the Loop (HIL) system where the power converter has been replaced with an embedded system based on a FPGA board. The proposed system has been designed to test converter control algorithms in a fast and safe way. The proposed solution exploits an environment software platform with a high level abstraction, obtaining a good trade-off between accuracy and hardware resources, also allowing a faster prototyping procedure. The HIL implementation has been compared with that of the experimental rig, confirming a good agreement in terms of accuracy and dynamic behavior.
