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
Design of a High-Efficiency, High Specific-Power Three-Level T-Type Power Electronics Building Block for Aircraft Electric-Propulsion Drives
TL;DR: The design and fabrication procedure of a modular dc–ac three-level t-type single phase-leg power electronics building block (PEBB) rated for 100-kW, 1-kV dc-link is reported for the first time.
Journal ArticleDOI
Design and Evaluation of Laminated Busbar for Three-Level T-Type NPC Power Electronics Building Block With Enhanced Dynamic Current Sharing
TL;DR: This article focuses on providing the laminated busbar design guidance for a three-level T-type neutral-point-clamped (3L-TNPC) inverter to achieve low stray inductance and balanced inductance distribution between paralleled power switches to achieve equalized dynamic current sharing.
Journal ArticleDOI
Space-Charge Accumulation and Its Impact on High-Voltage Power Module Partial Discharge Under DC and PWM Waves: Testing and Modeling
TL;DR: In this article, a high-voltage dc and pulsewidth modulation (PWM) excitations between different terminals during different switching intervals are investigated. And the authors provide a group of PDIV comparisons of packaging insulation under dc and PWM waveforms and discloses discrepancies in these PDIV results with respect to their excitations.
