Blog Article

After several decades of technological evolution, power electronics applications have become extremely important for electric/hybrid propulsion systems, smart grids, renewable energy systems, energy saving, and bulk energy storage, besides the typical applications in industrial automation and high-efficiency energy systems.In all these applications, a power conversion system with high efficiency and power density is required without sacrificing the system's power quality.The paper describes the specific characteristics and the scalar modulation strategy Jewelry of a new multi-level multiplexed inverter topology for medium-voltage AC applications.The proposed power converter configuration is intended for high-power applications aiming to reduce the active device's voltage rating and losses exhibiting a resulting low switching frequency of the power switches.

The proposed modulation strategy aims to reduce the 1.5" x 9" computational burden and simplify the implementation process, which are at the basis of any possible industrial adoption.Simulation results and full Hardware-In-the-Loop verification support the analysis.The Hardware-In-the-Loop assessment has enabled the development of a suitable modulation strategy, and the testing of the power converter is a safe environment.
