Dual-output isolated DC-DC converters in the R1DX series by Recom offer a choice of ±5V, ±9V, ±12V or ±15V bipolar outputs. The converters are now available from  Dengrove Electronic Components. The open-frame, surface-mount power modules measure 15.2mm x 10.7mm and are 8.0mm high and capable of driving capacitive loads of up to 1000µF. Their size and capacitance make they suitable for applications such ...

GaN Systems CEO Jim Witham will present two papers on the use of GaN power devices in automotive systems at Electronica nexts week. “Automotive is one of the central themes at Electronica, with a dedicated Automotive Forum,” said the firm. “The demand and impact of electric and autonomous vehicles has underlined the importance of power electronics throughout the entire automotive and ...

Fujitsu has developed a crystal structure that  increases both current and voltage in GaN HEMTs, effectively tripling the output power of transistors used for transmitters in the microwave band.  GaN HEMT technology can serve as a power amplifier for equipment such as weather radar.  By applying the new technology to this area, it is expected that the observation range of the ...

Toshiba has introduced a bipolar driver for two-phase stepping motors up to 44V 5A that includes 1/128 micro-stepping. TB67S128FTG, as it is to be known, also supports full, half, quarter, 1/8, 1/16, 1/32 and 1/64 step operation – micro-stepping is by PWM, using sine-wave derived on-off ratios – output chopping frequency can be adjusted by external resistance and capacitor. Power dissipation ...

Harting has introduced a range of current sensors which can be directly mounted on busbars.   With dimensions of 6cm in height and 14cm wide, the HCME range of current sensors measure high currents up to 5500A.  The design of the HCME sensors is based on the open-loop measurement principle. This provides a direct representation of the primary current with ...

A fast charging station for electric cars, capable of delivering 350kW to each of several vehicles

Recom has added the RSP-168 surge protectors to their portfolio, which allow DC/DC converters to meet both RIA12 and NF F 01-510 surge immunity specifications for railway applications.  Three versions cover a range of railway certified DC/DC converters from 20W up to 240W.  The modules are designed to protect railway DC/DC converters from excessive voltage surges of up to 385VDC.  ...

The EU may have lost the race to have an  EV battery industry before it got off the ground. In May last year, the EU launched the European Battery Alliance aimed at getting European  companies to build 10-20 battery factories. Only one European company plans to build a factory – NorthVolt of Sweden. Meanwhile foreign companies are  racing to set ...

Efficient Power Conversion (EPC) has completed automotive AEC Q101 qualification for two GaN devices. Two of the company’s eGaN FETs, the EPC2202 and EPC2203, underwent environmental and bias-stress testing, including humidity testing with bias (H3TRB), high temperature reverse bias (HTRB), high temperature gate bias (HTGB) and temperature cycling. The company reports that the wafer level chip scale (WLCS) package has ...

SiC devices offer dramatic improvements over silicon IGBTs in power conversion applications above 600V, say Paul Salter and Joe Petrie of Pulse Power and Measurement. In applications such as inverters, motor drives and battery chargers, silicon carbide (SiC) devices offer advantages such as higher power density, reduced cooling requirements and lower overall system cost. Although an SiC device costs more ...
