STMicroelectronics has a 650V GaN transistor half bridge sharing a package with drivers and control logic – describing it as “the world-first platform embedding a half-bridge driver based on silicon technology along with a pair of  gallium-nitride (GaN) transistors”. ST has named it MasterGaN1, and is aiming it at consumer chargers and power adaptors, and industrial applications up to 400W. GaN ...

Effective from today, Arrow Electronics has expanded its distribution agreement with power component manufacturer, Vicor, following the signing of a global distribution agreement. An earlier distribution agreement was limited to Europe, Middle East and Africa. Vicor designs and manufactures modular power components and packaging for computing, telecommunications and network infrastructure use, as well as industrial equipment and automation, vehicles, transportation ...

Electrification has created a new paradigm in automotive power systems; whether the design is a hybrid electric vehicle (HEV) or fully electric vehicle (EV), there are new design challenges to address. This technical article highlights some of the primary challenges in high-voltage current sensing and shares additional resources to aid and simplify your design process. For an introduction to current ...

Modular DC/AC inverters by Cotek Systems in the SR-1600-Plus series are suitable for industrial, telecomms and datacomms applications, renewable energy as part of rackmount systems or as standalone units. They are available from Relec Electronics. They feature Modbus communication, in addition to simple network management protocol (SNMP). The RS-485 Modbus port allows users to control and monitor parameters, such as ...

Engineers designing power systems today are under constant pressure to deliver ever higher levels of power, while also being constrained by size, weight, and cost considerations, writes Vicor. Introduction The defence sector, for instance, contains many applications where all these factors count, with an added requirement for high reliability. Examples include ground based vehicular systems, targeting systems, radar, and airborne ...

State of the art AC motor control applies power switch transistor arrays, steered by a microcontroller for all dynamic parameters.

TDK-Lambda’s 3 x 5inch CUS400M ac-dc PSUs deliver 250W when convection-cooled and 400W when force-cooled. UPDATE: Five more output voltage options have been added They are qualified for industrial and medical use. Initially, 12V and 24V outputs are available, with 15V, 19V, 28V, 36V and 48V models due later this eyar. All models accept 85 to 264Vac inputs and have a ...

Klaus Neuenhüskes, of Toshiba Electronics Europe GmbH, considers the challenges in power delivery and heat dissipation that have to be solved to a large part by the automotive silicon vendor.

Pre-Switch, the company which developed a artificial intelligence (AI) DC-AC, AC-DC soft switching controller has announced that Foxy Power will be its exclusive sales partner. The Berlin-based business development specialist will promote Pre-Switch’s technology to minimise switching losses in industrial, automotive and alternative energy applications as well a in appliances. Pre-Switch’s technology uses AI to constantly adjust the relative timing ...

Claimed to be the smallest 3W AC-DC power modules available to date, the RAC3 series by Recom is now available from Dengrove Electronic Components. The modules measure 28.5mm x 23.5mm x 17.9mm and deliver full load power from  -40°C to 60°C, and 2 Watts up to 80°C.  The modules also meet the latest European ErP Lot 6 ecodesign specifications for ...
