CUI has added a 2-W series to its second generation of isolated dc-dc converter family, designed to deliver improved efficiency, isolation, and thermal performance compared to previous versions.  The unregulated PDS2-M series is packaged in the same compact eight-pin surface-mount (SMT) package as the existing 1-W PDS family, measuring 12.7 by 11.2 by 7.25 mm. The modules feature 1.5-kV dc

Tesla Motors passed an important milestone in June as its rapidly expanding Supercharger network delivered more than one gigawatt hour of power (GWh) to Model S electric vehicles – that’s enough energy for 3.7 million electric miles! According to Tesla’s blog, the achievement saved 168,000 gallons of gas and offset 4.2 million pounds of carbon dioxide. Since the Superchargers were

Researchers at the University of California, Riverside’s Bourns College of Engineering have created a lithium ion battery that outperforms the current industry standard by three times. The key material: sand. Yes, sand. “This is the holy grail – a low cost, non-toxic, environmentally friendly way to produce high performance lithium ion battery anodes,” said Zachary Favors, a graduate student working

Diodes Inc. has introduced new space-saving package options for its ZXTR2000 series of high-voltage linear regulator transistors designed for 48 V circuits in networking, telecom and power-over-ethernet equipment. By monolithically integrating several discrete components into the ultra low profile PowerDI®5 and the higher power dissipation TO252 (DPAK) packaging, the regulator transistors offer designers the opportunity to increase power density in

One of the first Tesla Model S owners in China, Andrew Zong, had a moment of perhaps unwelcome clarity shortly after picking up his vehicle in Beijing… when he realized that it was more or less impossible to drive it back to Guangzhou, owing to the country’s lack of charging infrastructure. Rather than simply accepting the situation, and having his

The NXP TEA1732CTS is a low cost Switched Mode Power Supply (SMPS) controller IC intended for flyback topologies. The TEA1732CTS operates in peak current and frequency control mode. Frequency jitter has been implemented to reduce ElectroMagnetic Interference (EMI). Slope compensation is integrated for Continuous Conduction Mode (CCM) operation. The TEA1732CTS IC features OverPower Protection (OPP). The controller accepts an overpower

Zero Voltage Switching， Class-D amplifier featuring either the 40-V EPC2014 or the 100-V EPC2007 eGaN FET. The source board is configured in an optional half-bridge topology (for single-ended configuration) or default full-bridge topology (for differential configuration), and include the gate driver(s) and oscillator that ensure operation of the system at 6.78 MHz. These amplifier boards are available separately as EPC9506

Funded by the German Federal Ministry of Education and Research (BMBF), the research project “NEST-DC” aims to investigate the foundations of an innovative semiconductor-based and completely electronic circuit breaker for dc micro grids and applications. The new circuit breaker should be able to switch direct current on, and most importantly switch it off, as quickly and safely as possible at

Honda revealed that some hybrid versions of its Fit and Vezel subcompacts could suddenly accelerate without warning. A Honda spokesman in Tokyo told Bloomberg that unintended acceleration incidents have caused property damage, but no injuries or deaths thus far. The recall affects only vehicles that were sold in Japan. Anthony Anderson, a UK electrical engineering consultant, told EE Times, “To
