Versatile automotive 48-V electrical systems will reduce CO2 emissions and make practical super-efficient electrical subsystems. Joseph Pulomena, EPCOS, a TDK Group Co. NEARLY five years ago, the U.S. government issued rules requiring automakers to hit a fleet average of 54.5 mpg for new cars and trucks – nearly doubling average fuel economy. Electric vehicles and […]

Are power systems up to the task of running self-driving cars?
Automotive electronics depends on power supplies that can handle abuse like load dumps. New ICs are optimized for these extreme environments and can meet stringent vehicle safety standards. Tony Armstrong, Analog Devices Inc. THE auto industry expects a transition to autonomous vehicles via both an evolutionary path, where existing cars get there little by little […]

With the MagI³C VDRM, Würth Elektronik eiSos introduces a new DC/DC voltage converter in the MagI³C power module family in a TO263-7EP package. The input voltage range of the converter covers the range from 6 to 42 V to allow conversion from the 9 V, 12 V or 24 V industry bus. The product family is […]
Immediate availability of i3A series non-isolated DC-DC converters
Sager Electronics, is now stocking i3A Series of 100W non-isolated DC-DC converters. TDK-Lambda’s i3A power modules perform local voltage conversion from a 12V, 24V, or well-regulated 48V bus. The i3A series utilizes a low component count that results in both a low cost structure and a high level of performance. The open-frame, compact 1/32nd brick design features […]
10-W DC/DC converters in DIP-16 package handle inputs over a 4:1 range
TRACO POWER has announced the release of their TEL10WI series of 10 watt DC/DC converters in the DIP-16 package measuring 0.94 x 0.54 x 0.31”, the series sets the new standard for 10 watt power density with 3.83 W/cm3. Approved to UL62368-1 & UL60950, the TEL10WI are economical solutions for space critical and cost sensitive […]
The benefits of silicon carbide in dc/dc converters
Adil Salman from Wolfspeed recently shot a video with us covering a silicon carbide charging circuit demonstration. The charger used Wolfspeed SiC MOSFETs. It had two stages. One is a PFC (power factor correction) stage, the other is an LLC converter stage. If you were to try building a similar charger with silicon IGBTs, you […]
SMPS chips from Analog Devices squelch EMI
We recently filmed a short video with Tony Armstrong from Analog Devices who took us through a demonstration of a new kind of circuitry that cuts down the noise from switching power supplies. Switchers are notoriously noisy but can usually be fixed with filtering. Armstrong illustrates that with a non-synchronous regulator running at about 300 […]
Current-compensated ring core powerline double chokes target dc link apps in frequency converters
TDK Corporation presents a new series of EPCOS current-compensated ring core powerline double chokes. The RoHS-compatible B82724J8*N040 series features a high rated voltage of 800 V DC or 250 V AC in continuous operation and was developed specifically for use as DC link chokes in frequency converters. A further advantage of the new series is its […]
