Chilicon Power announces the CP-100 Gateway, a 7″ capacitive-touch tablet that provides powerline communication (PLC) to CP-250 microinverters with integrated Wi-Fi and zWave wireless modules. The CP-100 is a user friendly monitoring appliance for every residential and commercial solar array. Chilicon powerline communication has been built ground-up by former NASA engineers using advanced signal processing […]

Ceramic capacitors work to 200°C temperatures
KEMET Corporation (NYSE: KEM), a global supplier of electronic components, introduced its new High Temperature Radial Molded Multilayer Ceramic Capacitors which offer industry-leading performance in extreme environments and high temperature up to 200 degrees Celsius. These capacitors are designed specifically to withstand the severe shock and vibration conditions associated with deep-well and horizontal drilling activities, […]
Super-accurate power/energy monitor for DC supply rails handles 100V
Linear Technology Corporation introduces the LTC2946, a high or low side charge, power and energy monitor for DC supply rails in the 0V to 100V range. An integrated ±0.4% accurate, 12-bit ADC and external precision time base (crystal or clock) enables measurement accuracy better than ±0.6% for current and charge, and ±1% for power and energy. […]
Compact fuse for high-wattage smart phones
Littelfuse, Inc. has introduced the compact 777 Series Fuse to provide protection for higher-wattage wall-mount chargers for battery-powered electronic equipment. Although chargers for earlier generations of mobile phones had relatively low wattage (typically about 5W), today’s highly compact chargers must often be able to handle 10-15W of power, which requires withstanding higher levels of current. […]
Gallery: Scenes from the IEEE ECCE conference
The IEEE Energy Conversion Congress and Exposition took place last week in Pittsburgh. The clear trends based on exhibits on the show floor included a lot of interest in SiC power devices and in alternative topologies for inverters. Here are a few of the more interesting sites we encountered there. SiC on display The Center […]
New high-voltage technology site developed by Mouser
The Technology section provides an easy to understand overview of this field, including how high voltage is defined differently depending upon the applications field and the importance of designing with safety in mind. The Articles section discusses important considerations when designing at high voltages, including Design Guidelines for Optocoupler Safety. The Technical Resources section lists […]
Corrosion-resistant conductors clad to specification
Custom manufactured corrosion-resistant conductors for use in batteries, fuel cells, petrochemical, power generation, remote power, and alternative energy applications are available from Anomet Products of Shrewsbury, MA. Anomet Corrosion-Resistant Clad Conductors feature an OFHC copper core to provide uniform current distribution and a metallurgically bonded clad exterior layer to achieve specific environmental performance capabilities. Designed […]
700-V switched supply targets smart meters, home automation
Expanding its portfolio of high-voltage power solutions for offline AC/DC designs, Texas Instruments (TI) (NASDAQ:TXN) introduced a 700-V switcher with the industry’s lowest quiescent current of less than 100 uA – half the power consumption of existing solutions. The UCC28880 controller integrates a 700-V power MOSFET and high-voltage current source, increasing overall energy efficiency of […]
Low-capacitance diodes help thwart ESD
Littelfuse, Inc. has introduced the low-capacitance SP3014 Series TVS Diode Array (SPA® Diodes), to provide protection for electronic equipment that may experience destructive electrostatic discharges (ESD). The SP3014 Series, which integrates two channels of low capacitance steering diodes and a zener diode, can safely absorb repetitive ESD strikes above the maximum level specified in the […]
Switching regulator fundamentals – the SEPIC converter
OK, so maybe it’s not the logical follow-on from the buck converter but nevertheless a useful converter and probably a bit more interesting than the boost converter. The SEPIC – Single Ended Primary Inductance Converter – is useful because while a buck converter allows you to step down the voltage and a boost converter allows […]
