Abstract

This article shows the study of the most commonly used modeling techniques in the literature to perform real-time simulation and its possible subsequent use in a Hardware In the Loop (HIL) system, applied to power electronics converters.Each of the most used methods and how to find the equations associated with them for further programming are explained in detail.As a case study, the synchronous buck converter was selected, showing in detail the solution of this circuit by the state space technique and modified nodal analysis.The results obtained using the techniques are compared against a simulated converter in the well-known and accepted PSIM software.

Keywords: Hardware in the loop (HIL), Modeling, Modified Nodal Analysis (MNA), Real Time Simulation, State Space.
