Abstract
ESTRADA, L. et al. Practical considerations for HIL simulations of power converters using different numerical methods. J. appl. res. technol [online]. 2023, vol.21, n.6, pp.899-911. Epub Aug 13, 2024. ISSN 2448-6736. https://doi.org/10.22201/icat.24486736e.2023.21.6.1816.
The use of hardware in the loop systems implemented in FPGAs is constantly growing due to their performance. However, hardware implementation of numerical methods to solve differential equations presents some challenges when applied to power converters. This paper shows a comparison of several numerical methods: Euler, Heun, Midpoint, and fourth order Runge-Kutta, considering the accuracy of the methods and how they can be applied to power converters, where the equations change depending on the status of the switches. Results show that the speed in the solution of the numerical method is the main variable that affects the accuracy of the simulation, so to keep a fast resolution speed numerical method with low resources should be used.
