Emulator Based on Switching Functions for a Dual Interleaved Buck-Boost Converter

الملخص EN

Under the unavailability of some components of a complex system, the Hardware In the Loop (HIL) tool allows the emulation of other subsystems.

When these devices are not available, a customized emulator can be developed based on the Piecewise Linear Model (PWLM) and a numerical method for solving the differential equations system.

However, these implementations require the use of a Field Programmable Gate Array (FPGA) with extensive hardware resources.

In this article we propose the use of switching functions for the modeling of power converters of a Hybrid Power System (HPS), allowing the reduction of hardware resources of the FPGA, and the number of steps per switching cycle is increased.

The results are compared with SABER simulations and a PWLM evaluated with the Euler method.
