  GaN transistors have been designed for critical applications in the high reliability or commercial satellite space environments. The family of 40 to 300V radiation hardened (rad-hard) GaN transistors are by EPC Space and range from 4.0 to 30A.

Rittal was approached by Powerfish, a Scottish-based panel builder and electrical engineering business, with a brief to design and deliver robust, flexible, and easy-to-install panels for a renewable energy customer. The VX25 Ri4Power panels were the result.

A few weeks ago Fronius International launched the Symo GEN24 Plus solar inverter which uses CoolSiC MOSFETs. Its Multiflow technology makes it suitable for a wide range of applications supporting energy self-sufficiency. Not only does it provide power for direct use in the household, but it also offers an interface for energy storage systems.

The TMR 4 and TMR 4WI are a set of regulated four watt DC/DC converters with either 2:1 (TMR 4) or 4:1 (TMR 4WI) input voltage range. They come in a compact SIP-8 package featuring single and dual output models, I/O isolation voltage of 1600 VDC and protection against short-circuit and over load.

STMicroelectronics has added a QML-V qualified 7A DC/DC point-of-Load converter to its growing portfolio of radiation-hardened (rad-hard) integrated power products that deliver high power efficiency to satisfy the most demanding space applications.

XP Power has announced the introduction of the SVR surface mount and VR through-hole, non-isolated DC/DC switching regulators. With efficiencies of up to 96% and operating temperatures of -40 to +85°C, the Point of Load (PoL) devices are ideal as replacements for low efficiency linear regulators.

LEM has launched its new DC meter solution, a smart and compact DC Billing Meter (DCBM), fully compliant with the German ‘Eichrecht’ regulation. The DCBM is a smart and compact billing solution that will help electric vehicle charging stations take advantage of the benefits of DC charging.

Hybrid and all-electric drive technologies are expected to continue to gain market share, which will also increase the need for suitable test tools of the energy storage systems used. Lithium-ion packs which are typically used in electric cars usually weigh between 200 and 700kg or even more.

The new Power Dynamics (PDI) watertight Power Stanchion series designed for harsh environments and rugged applications is in stock at New Yorker Electronics.

Texas Instruments has expanded its high voltage power management portfolio with the next generation of 650V and 600V Gallium Nitride (GaN) Field-Effect Transistors (FETs) for automotive and industrial applications.
