Energy efficiency and power density become main qualitative indexes of power electronic systems.
Optimising bipolar plate and membrane electrode assembly material and design configurations, Horizon's Shanghai R&D center has successfully achieved a continuous power density of 1.5W/cm2 at 0.6V per cell in a full size short stack, doubling the power density of some commercial automotive fuel cells.
To obtain longer flight time and range, lighter structures and higher power density are essential.
"Working with cutting-edge, silicon-carbide power electronics, our research team uses a holistic design approach to develop a solar inverter that will achieve higher efficiency and power density, an extended service life and lower long-term costs," Zhao said in a news release.
The researchers of Sunrise Power, which is partly held by an institute of the academy, are also developing fuel cell modules with higher power density and lower cost.
Dielectric is also preparing broadcasters for ATSC 3.0 with its FutureFill feature, which increases power density by 7-to-9dB close to the tower, and reduces the main lobe gain by 1.2-to-1.4dB.
The power density of those engines was quite low for the present standard, in the range 20-30 kW/l, with the highest values reached by first turbocharged engines then appearing on the market.
The company says the M12 Power is a high performing M12 connector, it is a reliable solution for to linear drives, stepper motors as well as power supply lines for field bus modules and it is a compact alternative to 7/8in connectors in applications that require high power density. The new MQ15 X Power is a very compact and high performing connector that is suitable for power distribution and enables secure connection of devices such as AC/DC motors to 7.5kW (depending on system dimensioning).
By addressing these issues, the new yarn battery exhibits one of the best performances to date, including a power density similar to that of supercapacitors, as well as an energy density and capacity similar to that of conventional batteries.
We quantified the lowest immobilization threshold as measures of power density ([micro]W/[cm.sup.3]) and voltage gradient (V/cm).
