Switching thyristor series is robust for EV on-board charging
The 16A silicon-controlled rectifier (SCR) switching thyristor series from Littelfuse is optimised for electric vehicle on-board charge (EVOBC) applications. The devices are claimed to offer "excellent" AC handling capability and surge robustness for input rectifiers.
SCR thyristor optimised for phase control applications
Global circuit protection company, Littelfuse, has introduced a series of 40A standard high-temperature silicon-controlled rectifier (SCR) thyristors that are suitable for use as switches for rectifier and phase control applications such as voltage regulator, heating and motor speed controls. The new SJxx40x series is the first SCR thyristor from Littelfuse capable of handling 600V, 40Arms and junction temperatures up to 150°C.
Powerstax awarded ISO 9001 on manufacturing facility
Industrial power solutions manufacturer, Powerstax, hasbeen awarded ISO 9001 on its recently combined manufacturing facility in Wickford, Essex.The long term home to the ‘Drake’ brand of power conversion products now also houses production of the Powerstax range of high efficiency DC/DC converters and front-ends and value-added system assembly. After due process the complete facility is now ISO 9001 approved.
Advanced bus converter upgraded to include burst-mode capability
The award-winning BMR458 third-generation 3E quarter-brick advanced bus converter from Ericsson Power Modules has been upgraded to integrate burst-mode operation, which enables the module to handle 1079W of peak power for a brief period of time, up to a maximum of one second.
Two-phase digital power factor corrector consists of AC/DC converter
Power semiconductors and integrated circuits manufacturer for energy efficiency, power management, and motor control applications, IXYS Corporation have announced the availability of a new design: 3kW Two-Phase Digital Power Factor Corrector (PFC). It is based on Zilog’s 8-bit Z8F6481 microcontroller, a member of the Z8 Encore XP F6482 series of microcontrollers, and IXYS power transistors and rectifiers.
Resistors, diodes address key design challenges
Resistors, capacitors and diodes to help design engineers optimise their end products and address key design challenges such as scale, performance and cost have been added to the Farnell element14 portfolio. They represent the Super 12 range which is released annually by Vishay and consists of six semiconductors and six passive components with advanced technology capabilities.
Original cable-car transit system introduced in Brest
Two cable cars have been boosting the urban mobility in the French city of Brest, since November, which can carry up to 60 people who travel more than 400m above the River Penfeld, with a power consumption that is potentially close to zero.Supported by Leroy-Somer, the companies Bartholet France and Seirel are behind this achievement which is a world first in terms of technology.
Powerstax relocates to offer customers economies of scale
One of Europe’s leading value-added and industrial power solutions manufacturers, Powerstax, is consolidating its two business divisions into a single facility in Essex.In 2012 Powerstax acquired the ‘Drake’ brand of power conversion products and their manufacturing facility in Wickford, Essex. From Monday 8th May 2017 both product ranges will be sold, manufactured and supported from this facility.
Stay lit with open LED protectors
A range of open LED protectors has been introduced by Littelfuse, the PLEDxN series. These surface mount devices, which are designed for use with high-brightness, 1W LEDs with a nominal 350mA current at 3V, provide a switching electronic shunt path when an LED in an LED string or array fails as an open circuit. They are designed to reset automatically if the LED heals itself or the power is cycled.
Duo of isolated eighth-brick DC/DC converters deliver on efficiency
A pair of DC/DC converter modules in eighth-brick formats has been launched by Ericsson, which are able to handle currents of up to 40A and deliver world-leading efficiency.Enabling reduced energy and cooling costs, these two modules are the most efficient 40A-class eighth-brick-format power modules in the industry: the PKB4211D and PKB4110D deliver respective efficiencies of up to 95.3% and 94.7%, with tightly regulated 5 and 3.3V outputs at 50%...
