The paper presents an approach to evaluate modulation techniques in a Grid-Tied two-level Inverter using Test-Driven Design (TDD). It presents a set of tests that collect and calculate performance, harmonic, and power metrics of the inverter, based on IEEE Standards. The results are obtained by a Hardware-In-the-Loop (HIL) simulation and the TDD is applied with the pytest framework and Python language. The results of TDD procedure offer a structure to analyze different characteristics of the modulation approaches considering the Half-Bridge converter and the Space Vector, Sinusoidal and Carrier-Based algorithms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
