DC/DC converters deliver reliability for railway applications
Murata is introducing the first in a series of encapsulated DC/DC converters designed specifically for industrial and railway applications from Murata Power Solutions. The IRQ series delivers the latest technology in fixed frequency power conversion available in the industry.
Switching regulators operate at up to 93% efficiency
A range of boost switching regulators that enable designers to power devices such as microcontrollers, radio modules, or energy-conscious IoT systems at up to 100mA for long periods from a single 1.5V cell is available at Dengrove Electronic Components. The RECOM R-78S 0.33W regulators ensure longer lifetime by maintaining a stable 3.3V output as the battery discharges as low as 0.65V.
Coupled inductors for automotive DC/DC converter applications
TT Electronics haslaunched the HA78D series of coupled inductors for use in DC/DC converter applications. With their high temperature rating and AECQ200 certification, they are ‘automotive ready’ for the latest generation of motor vehicles.
Energy storage made more efficient with 2kW power reference design
Texas Instruments has introduced the industry’s first 2-kilowatt (kW) isolated bidirectional DC/DC converter reference design for 48 to 400V Uninterruptable Power Supplies (UPS) and energy storage systems.
Smallest isolated 8W DC/DC Converter with ultra-wide input range
The new MDWI08 series of 8W Isolated/Regulated DC/DC converters has been announced by MINMAX with ultra-wide input ranges in the smallest/ultra-compact 16 pin DIP package measuring only 0.94x0.54x0.31”, that offers a very high power density up to 50W/in3.
We need a 'Giga-fab' for Gallium Nitride, somewhere
A new technology promises a revolution in the efficient use of electrical power. If widely deployed, this technology could have a significant impact on climate change by reducing our dependence on fossil fuel in favor of renewable energy. It could enable discontinuous advances in communications, electric vehicles and medical diagnostic equipment.
Keeping the noise down: Converter and inverter output filtering
Most modern power conversion topologies use switched-mode techniques for highest efficiency and smallest size and cost. Inevitably, switching noise is produced and output filters are required to minimise EMI and provide reliable operation of the power converter and load. This article looks at the effects of noise and some of the filtering techniques that can be used.
Selecting DC-link capacitors in power converters
In applications from the simplest cell-phone charger to grid-tied inverters operating at hundreds of kW, power conversion schemes are used which incorporate an intermediate stage where energy is processed at DC. A ‘DC-link’ capacitor is fitted at this point to provide a low impedance path for high frequency switching currents and to provide energy storage.
The reach of ‘More Electric Aircraft’ extended
A five year engineering research project is set to extend the application of electric technology to a wider range of aircraft.
Thick film chip resistors deliver increased accuracy
A new series of thick film surface-mount chip resistors have been introduced by Vishay Intertechnology, which feature four-terminal Kelvin connections and high power ratings of 0.33W in the compact 0306 case size. Offering a power density over 3.3x higher than standard devices in the 0603 footprint, Vishay DaleRCWK0306series resistors are designed to save space and reduce component counts in telecommunications, computer, industrial, and consumer ...
