High power semiconductor crowbar protector for AC power lines
AC power line disturbances are the cause of many equipment failures. The damage can be as elusive as occasional data loss or as dramatic as the destruction of a power supply, LED lightings, industrial system and consumer equipment such as ovens or refrigerators and television sets.
SiC diodes offer higher efficiency and lower system costs
With the introduction of a new family of 650V silicon carbide (SiC) Schottky diodes, ON Semiconductor has extended its SiC diode portfolio. The diodes’ silicon carbide technology provides higher switching capabilities with lower power losses and supposedly effortless paralleling of devices.
Power line conditioner protects downstream DC/DC converters
North Atlantic Industries, Inc. has announced the availability of the VPX55-3HU 3U, VPX Power Line Conditioner with Holdup. The VPX55-3HU is a 500 W, DC/DC power line conditioner that protects downstream DC/DC converters from MIL-STD 704B through F transients, low voltage conditions and power interruptions, and provides up to 50 milliseconds of holdup time at 500 W.
Protecting rechargeable Li-batteries in portable electronics
Littelfuse offers designers several protection devices to choose from in an array of form factors and device characteristics that meet the needs of their particular design. As sleeker designs and thinner portable consumer electronics become increasingly popular, Lithium-ion and Lithium- polymer batteries have become the 'go-to' power sources of choice in these applications.
Low resistivity PPTC to improve Li-ion polymer battery packs
Lithium-ion batteries (LIB) have now become part of the standard battery pack of choice used in most notebook, smartphone, e-reader, and tablet designs. The LIB chemistry produces optimal characteristics with regard to high energy density, low self-discharge, light weight, long cycle life, lack of memory effect, and low maintenance. LIBs are now gaining popularity in other market segments such as electric vehicl...
DC/DC converter family powers modern railway applications
The next generation of DCMs has been released by Vicor, with a family of wide input range (43–154V input) 3623 (36x23mm) ChiPs with power levels up to 240W and 93% efficiency, targeted at new rail transportation and infrastructure applications.
Synchronous rectifier controller delivers higher efficiency
Continuing its strategy to meet the industry-wide demand for increased power density and improved efficiency, Diodes Incorporated has introduced the ZXGD3113 synchronous rectifier controller. When coupled with a MOSFET, the pairing can be used to replace lossy Schottky rectifiers in power supplies based on a flyback or resonant converter topology.
Universal heavy current technology with maximum precision
The SINEAX DM5 series is the next generation of transducers introduced by Camille Bauer, which is a series of devices that are programmable universal measurement instruments for heavy current networks: classic high precision transducers for top hat rail mounting. They are suitable for almost any type of monitoring function and as well as for retrofitting in energy distribution and industry.
Automotive-grade high-voltage coupled inductors at APEC 2018
At the Applied Power Electronics Conference (APEC) being held 4-8th March in San Antonio, Texas, Coilcraft will debut its LPD8035V series of miniature, high-voltage 1:1 coupled inductors. The LPD8035V provides 1,500Vrms, one-minute isolation (hipot) between windings from a package that measures 7.92x6.4x3.5mm, providing users with significant size and cost reductions over conventional bobbin-wound alternatives.
Logic dividers deliver space-saving up to 93% for system efficiency
Nexperia has announced a new range of AHC (Advanced High speed CMOS) dividers with oscillators that save space, increase efficiency and reduce overall system cost. This new 74AHC1G42xx dividers range also offers overvoltage-tolerant inputs for mixed voltage mode operation, increasing reliability and flexibility in designs.
