Consisting of the TK31N60X, TK39N60X and TK62N60X, Toshiba has announced the introduction of the DTMOS IV-H series high-speed switching type super junction MOSFETs. The 600V MOSFETs are suitable for applications requiring high reliability, power efficiency and a compact design, such as high efficiency switching power supplies for servers and telecomms base stations and power conditioners for photovoltaic inverters.

The LT3752/-1 is a high input voltage capable synchronous forward controller with active clamp transformer reset from Linear Technology. The LT3752 operates over input voltages from 6.5-100V. For up to 400V inputs and greater, the LT3752-1 allows RC start-up from the input voltage with the maximum voltage limited only by the choice of external components, making it suited for HV/HEV automotive applications.

Implementing accurate cell monitoring and balancing without requiring a microcontroller in the (BMS) Battery Management System, ams have introduced a reference design for lithium pedelec/e-bike batteries. Battery pack and pedelec manufacturers who use the design will benefit from valuable BOM savings and a simpler circuit design.

In this week’s Nature Communications imec presents the development of fullerene-free organic photovoltaic (OPV) multilayer stacks achieving a record conversion efficiency of 8.4 percent. This breakthrough achievement is an important step to bring organic photovoltaic cells to a higher level in the competitive thin-film photovoltaics marketplace.

Believed to be the industry’s first commercially available family of 50A SiC rectifiers, Cree has announced the CPW5 Z-Rec high-power SiC Schottky diodes. The diodes are suitable for use in high power systems from 50kW to over 1MW, addressing applications such as solar / PV inverters, industrial power supplies, induction heating, battery charging stations, wind turbine converters and traction inverters.

Signalling an important step in lowering the cost of power delivered from offshore installations, GE Power Conversion has announced the successful trials of PassiveBoost - its technology to allow remote power networks to go DC. The technology also paves the way for increasing the electrical output delivered from renewable energy sources in distant, inhospitable places.

Held from 20-22 May 2014 in Nuremberg, Germany, PCIM Europe 2014 will present the latest trends in power electronics components and systems for use in the wind and solar energy sector. As well as the products and solutions on display at the exhibition, visitors will be able to attend vendor presentations and contribute to expert discussions on the latest developments in wind and solar energy at the free industry forums.

Satisying key battery management criteria for future-proof vehicle design, Isabellenhütte have announced the ICB-M current sensor. The company boasts that the sensor will deliver high-precision, redundant current measurement for consistently efficient energy control.

Designed to add the sound of a conventional combustion engine to EVs and HEVs, the TB2909FNG is a single-chip amplifier from Toshiba Electronics Europe. The device also supports other external audible output including reversing alarms and ‘answerback’ confirmation for keyless remote entry security.

The company's first synchronous SEPIC, inverting, boost and flyback multi-topology DC/DC controller, the LT8710 has been introduced by Linear Technology. The power IC is suitable for applications including lead acid battery chargers, automotive ECU power, solar panel power converters, high power local power supplies and wide input voltage range SEPIC/inverting.
