Navitas Semiconductor, a leader in GaN and SiC power semiconductors, has announced a partnership with BrightLoop to enhance the power density of their high-voltage, high-power 'multiverters' used in fuel-cell chargers for heavy-duty transportation. BrightLoop's latest series of hydrogen fuel-cell chargers incorporate Navitas' automotive qualified G3F SiC MOSFETs, enabling power conversion efficiencies over 98% and power densities up to 35 kW/kg and 60 kW/L. The collaboration aims to deliver exceptional performance in energy management scenarios for fuel cells and heavy-duty applications. Navitas' G3F SiC MOSFETs are integrated into BrightLoop's 250 kW HV-DC/DC converter, offering an impressive output of 950VDC at 480A, with the capability to be paralleled for megawatt power needs. The GeneSiC proprietary 'trench-assisted planar' technology ensures high-speed and cool-running operation, delivering efficiency and reliability in high-power applications. The article highlights the key features of Navitas' SiC MOSFETs, such as high-speed performance, lower case temperature, and extended product life compared to competitors. The technology enables low RDS(ON) increase versus temperature, leading to minimal power losses and up to 20% lower RDS(ON) under high-temperature operation compared to other products. Moreover, GeneSiC MOSFETs boast the highest-tested avalanche capability, longer short-circuit withstand time, and tight threshold voltage distributions, simplifying parallel connections. Leaders from Navitas and BrightLoop express their pride in the partnership, emphasizing the importance of efficiency, ruggedness, and reliability in delivering high-power density solutions for various industries. Both companies are dedicated to driving innovation in power electronics and enabling the development of next-generation converter technologies for demanding applications.
