Real-time emulation of a three-phase Vienna rectifier with DC voltage control and power factor correction.

The paper deals with the accomplishment of a FPGA-based dynamic model of a three-phase Vienna rectifier controlled in order to feature unity power factor operations. Such a model has been developed for the Hardware In the Loop (HIL) implementation of a test rig in which the power converter is replaced with an embedded system using a FPGA board. The proposed approach has been fostered mainly to test different converter control algorithms in a fast and safe way. Such solution is based on a software platform environment with a high-level abstraction that ensures a good trade-off between accuracy and hardware resources, also allowing a fast prototyping procedure. The results obtained by the HIL implementation have been compared with those of a fully hardware experimental rig, confirming a very good agreement in terms of accuracy and dynamic behavior.
