Various forms of ambient energy are available in most environments. Depending on the environment and the power needs of the device, common energy harvester choices include light harvesters, thermoelectric harvesters, and mechanical vibration harvesters. Each of these energy harvesting technologies can be optimized for maximum performance in a given environment. In the case of light […]
Next-generation shielding may absorb electromagnetic interference rather than reflect it
Engineers trying to shield RF-sensitive circuitry a few years from now may have the option of using material that absorbs RF energy rather than just reflecting it. So say researchers at Drexel University and the Korea Institute of Science and Technology. They are researching a class of material called MXenes, and more specifically, titanium carbonitride […]
Energy harvesting applications, architectures and the massive IoT
Wireless sensor nodes, wearables, trackers, and displays are typical devices that can be powered using energy harvesting (EH), also called ambient energy, energy scavenging, or power harvesting. The availability of ambient energy for harvesting varies depending on the location and environment where the device is used. Among the many possible sources of ambient energy, the […]
Dual-output railway quality supplies put out 250 W
ABSOPULSE Electronics has recently released the PFC 252R-HSA-F3 series dual-output railway quality power supplies with pure convection cooling. The 250W units employ active power factor correction (PFC) to convert a universal 95V to 264Vac input to two outputs. Output V1 provides any voltage 12V to 110Vdc/10A to 14A max; output V2 offers any voltage 5V […]
Capacitor assemblies excel at power supply filtering
Knowles Precision Devices, a division of Knowles Corporation, recently expanded its capacitor assembly offering with the release of its new SV series of capacitor assemblies for power supply filtering applications. The SV series is a vertically stacked ceramic capacitor, offering superior performance compared with aluminum or tantalum electrolytic capacitors, while also helping to reduce the overall circuit board […]
Compact, single-phase EMC block filter meet space and performance constraints
SCHURTER completes its portfolio of single-phase EMC filters with its FMBB EP series, launching a new generation of ultra-compact filters with high-performing attenuation. The new double-stage filter family is more powerful than typical filters, meeting the space constraints and performance requirements of today’s state-of-the-art electronic devices. Top-quality components, including right-sized film capacitors and chokes with […]
Pint-sized PoL dc-dc converters piggy backed with mixed-signal processors
Dialog Semiconductor plc announced a collaboration with TDK Corporation to include Dialog’s GreenPAK technology with TDK’s latest series of µPOL power solutions to create the world’s first single-integrated system power sequencing solution. Traditional discrete solutions currently available on the market require an extensive array of components, which reduces board space availability, impacts system reliability and […]
One-amp power modules include power-good signal
Würth Elektronik extends its MagI³C power module product family to include a compact 1 A version in LGA-6EP package. The special feature of the module (type 171010501) is the “power good” function. The module indicates on one pin whether the output voltage is in the nominal range. The signal for the correct output voltage can […]
Thermoelectric modules cool from 95 to 60 C in four seconds
Kyocera International, Inc. today introduced a compact, highly reliable thermoelectric cooling module specifically engineered for use in medical devices, scientific instruments, high-performance batteries, and other applications likely to encounter the most difficult active-thermal-management requirements. To support new medical advances, Kyocera’s thermoelectric modules can be used in the latest diagnostic, testing, and analysis equipment requiring temperature-controlled […]
