Milpitas, California-based thin-silicon solar company Solexel has obtained a round D funding of $31 million. The company now has secured just over $200 million in venture capital funding. The latest round is for helping it go into commercial production. The official press release says, “Investors in Solexel include Kleiner Perkins Caufield & Byers, Technology Partners, DAG Ventures, Northgate Capital, GSV
SolarReserve is bringing 20 MW of utility-scale solar power to El Salvador’s Acajutla plant, while advancing its share of the Latin American solar market. The Santa Monica, California–based company won El Salvador’s first ever utility-scale solar tender. The country’s energy and telecommunications regulator oversaw the bidding process. SolarReserve sees Latin America as a good growth market, according to
During the second quarter of 2014, Changelight ordered multiple TurboDisc MaxBright M GaN Metal Organic Chemical Vapor Deposition (MOCVD) Systems. In addition, Changelight purchased a TurboDisc K475 MOCVD system to expand its production of red, orange and yellow (ROY) LEDs. “In the past we have used competitive MOCVD equipment for the majority of our production of ROY LEDs,” said Professor
ADM Instrument Engineering introduces the GTH03, a new range of 3-in-1 carbon dioxide, temperature and humidity transmitters from EYC. Designed for use in various environmental monitoring applications such as air quality monitoring, HVAC systems, mine and tunnel warning systems and greenhouses, the GTH03 sensors feature a non-dispersive infrared carbon dioxide sensor, and an integrated CMOS temperature and humidity sensor. Key
RESEARCHERS from Stanford have successfully used a pure lithium anode in a lithium ion battery. The common lithium-ion batteries of today tend to use an anode made of graphite or silicon, with the lithium only used in the electrolyte. While a lithium anode could boost the capacity by four fold and lower the weight of lithium ion batteries, researchers were
TRUMPower has launched its 105W TMP105-20-LNR ac-dc medical-grade power adapter, which is set at 20V output voltage and specifically configured to charge Lenovo® ThinkPad® laptop computers. The power adapter comes with a rectangular slim tip plug with a signal pin, which is compatible with a lot of Lenovo® ThinkPad® models such as Helix, T431s, Edge E531, T440s, X1 Carbon, etc.
Vishay Intertechnology, Inc. today introduced a new series of high-power, surface-mount precision thin-film chip resistors. Built on aluminum-nitride (AlN) substrates, PCAN series devices offer power ratings of 2 W and 6 W in compact 1206 and 2512 case sizes, respectively. The AlN substrates of the Vishay Dale Thin Film resistors released today feature enlarged backside terminations to reduce the thermal
Qualstar Corporation has expanded its ac-dc power supply offerings by adding the high-efficiency slim-line DIN-Rail power supplies to its N2Power brand product portfolio. The DL Series of DIN-Rail power supplies range from 10W to 480W of power and feature universal input with brown out protection and a variety of output voltages. The slim-line dimensions and efficient design (up to 91%)
Silicon carbide is a route 99% efficiency in induction heating drivers, claimed Cree as it introduced a 300A, 1.2kV half-bridge module. Bolting straight into a industry-standard 62mm footprint, it includes two 5mΩ SiC mosfets and two SiC free-wheeling Schottky diodes, that drop 1.7V at 300A. “The power module is pin-compatible to 62mm half-bridge modules, including IGBT modules rated at 450A
In a typical ac-dc power supply, diode bridges do not control inrush current due to the output capacitor sudden charge at line plug-in. A high inrush current can cause several issues for the system like component failure (fuse, bridge diode, etc.), but it also represents an excessive current stress for the power grid. If nothing is implemented to limit the
