Multiple current amplifier-based gate driving for parallel operation of discrete SiC MOSFETs
(Wiley, 2022-03)
The shorter switching times of silicon carbide (SiC) MOSFETs enable power converters to operate at higher frequencies than with silicon IGBTs. However, because SiC MOSFET die sizes are still relatively small, several devices ...
Decontamination of Ti Oxide Surfaces by Using Ultraviolet Light: Hg-Vapor vs. LED-Based Irradiation
(MDPI, 2020-10-22)
C-range Ultraviolet (UVC) mercury (Hg)-vapor lamps have shown the successful decontamination of hydrocarbons and antimicrobial effects from titanium surfaces. This study focused on surface chemistry modifications of titanium ...
Common-mode voltage mitigation in multiphase electric motor drive systems
(Elsevier, 2022-04)
Common-mode voltage (CMV) produces serious reliability and electromagnetic interference (EMI) issues in modern pulse-width modulated (PWM) electric drives. Such issues will become more prominent in the near future, as ...
Surface Activation of Titanium Dental Implants by Using UVC-LED Irradiation
(MDPI, 2021-03-05)
Organic contaminants significantly limit the bioactivity of titanium implants, resulting in the degradation known as the ageing of titanium. To reactivate the surfaces, they can be photofunctionalized, i.e., irradiated ...
Influencia de las modulaciones PWM en las pérdidas de potencia de los condensadores del DC-Link en inversores VSI multifásicos
(2022)
En aplicaciones de tracción eléctrica, los accionamientos multifásicos se están convirtiendo en una alternativa a tener en cuenta frente a sus homólogos trifásicos, debido a una serie de ventajas que compensan su coste ...
Interleaving Modulation Schemes in Asymmetrical Dual Three-Phase Machines for the DC-Link Stress Reduction
(MDPI, 2023-02-10)
The DC-Link capacitor plays a crucial role as far as power density and reliability are concerned: it occupies approximately 40% of the inverter, and causes approximately 30% of its failures. Asymmetrical dual three-phase ...
Reducción de la corriente por el condensador del DC-link mediante modulación e interleaving para máquinas asimétricas duales trifásicas
(2023)
El condensador del bus de continua (bus d.c.) desempeña un papel fundamental en lo que respecta a la densidad de potencia y la fiabilidad del inversor. Los accionamientos de máquinas asimétricas duales trifásicas (asymmetrical ...
Influence of PWM modulations on the DC-Link capacitor power losses of multiphase VSIs
(IEEE, 2022-12-09)
In traction applications, particularly in transport electrification, multiphase drives are increasingly being an interesting alternative over their three-phase counterparts due to a range of advantages outweighing the ...
