  • Digital controllers of power converters are more and more implemented in FPGAs due to the increasing complexity of current control algorithms, higher switching frequencies, and concurrence requirements. System behavior depends not only on the control algorithm but also on the implementation issues. Thus, closed-loop controller evaluation at early design stages is a main concern. In this paper, a new hardware-in-the-loop method is proposed. It profits from FPGAs and their design tools in order to validate the closed-loop power converter before prototyping the power stage. The proposed solution presents a general architecture that does not depend on specific vendors or CAD tools, but it uses those utilized for the final implementation of the controller. A case study is presented with a given implementation of the proposed solution. Comparisons with existing alternatives show the advantages of our approach.
