Cost-effective and versatile Hardware-in-the-Loop system for DC/DC converter emulation in education and research

This work presents a cost-effective, versatile hardware-in-the-loop (HIL) system for non-isolated DC/DC converter emulation. The system emulates five types of converters (Buck, Boost, Buck-Boost, Cuk, and SEPIC) and targets educational and research applications. The hardware uses an ARM Cortex M7 microcontroller to perform real-time calculations and produce analog signals that emulate the behavior of the converters. Its economical, compact, and modular design is optimized to facilitate use in educational environments and research projects with limited resources. Additionally, the system includes software that enables automatic configuration of the code necessary for emulation, offering flexibility while reducing costs and complexity.
