Adaptive Multi-Level Active Gate Drivers for SiC Power Devices
Shuang Zhao,Audrey Dearien,Yuheng Wu,Chris Farnell,Arman Ur Rashid,Fang Luo,Homer Alan Mantooth +6 more
TL;DR: A novel three-level (3-L) AGD for SiC power mosfet trajectory control has a shorter turn-off delay compared to any existing methodology and a comprehensive datasheet-driven trajectory model for the online model-based optimization of the 3-L turn- off is introduced.
Journal ArticleDOI
Busbar Design and Optimization for Voltage Overshoot Mitigation of a Silicon Carbide High-Power Three-Phase T-Type Inverter
TL;DR: In this article, the busbar design for a 250-kW SiC three-level T-type inverter is investigated, and a hybrid busbar structure with printed circuit board based buffer circuit using high-frequency decoupling capacitors is designed and evaluated.
Journal ArticleDOI
Internal Model-Based Disturbance Observer With Application to CVCF PWM Inverter
Yuheng Wu,Yongqiang Ye +1 more
TL;DR: In IM-DOB, a novel IM-based disturbance estimation observer is proposed to estimate the disturbance both in the low-frequency region and at harmonic frequencies, while compensation filters are introduced to enhance the robustness and stability.
Journal ArticleDOI
An Intelligent Versatile Model-Based Trajectory-Optimized Active Gate Driver for Silicon Carbide Devices
TL;DR: An intelligent versatile active gate driver (AGD) is proposed to achieve optimized switching trajectory for power devices and can provide more switching speed adjustment resolution than the other AGDs allowing for fine tuning of the switching speed of SiC power devices.
Journal ArticleDOI
Design and Validation of A 250-kW All-Silicon Carbide High-Density Three-Level T-Type Inverter
TL;DR: In this article, the authors presented a comprehensive design and validation of a compact all-silicon carbide (SiC) 250-kW T-type traction inverter with a power density of 25 kW/l and 98.5% peak efficiency.
