Abstract

This paper presents the design of an 800 V 11 kVA three-level three-phase active neutral point clamped inverter, utilizing 650 V gallium nitride enhancement-mode high-electron-mobility transistors, to evaluate its feasibility in electric traction systems. The modular approach of the presented power converter design is detailed discussed and the different printed circuit boards composing the power converter are presented, together with critical design issues. The paper includes the gate driver design, as well as the thermal analysis and parasitics extraction using ANSYS Q3D. Extractor., Comment: 6 pages, 9 figures, 15th International Conference ELEKTRO 2024. This work has been carried out in the framework of the ECSEL-JU Project GaN4AP (Gallium Nitride for Advanced Power Applications) - Grant Agreement No.101007310

24. A Reduced Switch Count, Self-Balanced, 13-Level Inverter Based on a Dual T-Type Configuration

Author

Foti, Salvatore, Scimone, Tommaso, Oteri, Antonio, Scelba, Giacomo, and Testa, Antonio

Abstract

A new dual T-type 13-level inverter topology is presented in this article, featuring less power switches, gate drivers, and diodes, than inverters based on traditional multilevel topologies, such as neutral point clamped, flying capacitor, T-type and cascaded H-bridge, or previously proposed reduced switch count 13-level inverter topologies. Moreover, no additional circuits are required to equalize the voltage of capacitors present in each pole, nor complex modulation strategies, leading to a reduction of cost and power losses. Exploiting a nearest level modulation technique, the proposed topology performs well in terms of efficiency and total harmonic distortion, as confirmed by experimental tests.

25. Multi-Physics Models of a Low-Voltage Power Semiconductor System-in-Package for Automotive Applications

Author

Mauromicale, Giuseppe, Calabretta, Michele, Scarcella, Giuseppe, Scelba, Giacomo, and Sitta, Alessandro

Abstract

Power converters and semiconductor devices are spreading their application fields, due to new renewable energy and automotive frameworks. In the electrified vehicles context, the even more stringent requirements, both in terms of performances and reliability, pose new challenges in the design phase of power switches. This paper analyzes, by means of finite-element simulations, a low-voltage power semiconductor system-in-package devoted to automotive applications, which integrates a MOSFET-based half bridge and a controller. Three simulation physical domains integrated in a unique flow are considered: thermo-mechanical, electromagnetic, and thermal numerical models. The aim is to develop a new comprehensive methodology which starts with a thermo-structural simulation of the package, then computes the on-state resistance and parasitic components to assess the electrical behavior of the package. Finally, a simulation check is made to verify if the power device performances are thermally consistent with applicative conditions.
