TL;DR: The detailed design, implementation, and demonstration for a silicon carbide (SiC) 150-kW TAB converter for solar-plus-storage applications are presented and a comprehensive characterization of the SiC gate driver with various external gate resistances is performed to improve the system efficiency.
Journal ArticleDOI
A Virtual Space Vector-Based Model Predictive Control for Inherent DC-Link Voltage Balancing of Three-Level T-Type Converters
TL;DR: This article proposes a new FCS-MPC, which only uses voltage vectors and virtual voltage vectors that do not affect the neutral-point voltage of the VSC dc link, such that an inherent dc-link voltage balancing can be achieved.
Journal ArticleDOI
Efficient Wireless Power Charging of Electric Vehicle by Modifying the Magnetic Characteristics of the Transmitting Medium
TL;DR: In this paper, a modified cement composite is used for covering the transmitting antenna area and using high frequency wide bandgap switches, which can transfer a high amount of power in a short time.
