Ultra-soft IGBT freewheeling diodes offer low losses
Infineon Technologies Bipolar GmbH & Co. KG has launched a diode family designed for modern IGBT applications: Infineon Prime Soft. This diode features an improved turn-off capability which now rates at 5kA/µs. Prime Soft builds on the IGCT freewheeling diode family which is based on a monolithic silicon design. Typical applications for the diodes are HVDC/FACTs and medium voltage drives using voltage source converters. These applicatio...
Smart thermostat design with SimpleLink WiFi
Learn how to create a low power, connected MCU-based smart thermostat to link a variety of sensors securely to the cloud to enable remote monitoring and control.
Power quality in hybrid operating theatres
If you told a NHS director of finance that they could reduce patient operating times and reduce the time that in-patients spend in hospitals, they’d most likely snap your hand off. This could soon become a reality with the introduction of hybrid operating theatres, which combine high end imaging equipment with a traditional surgery environment. However, there are several considerations that must be made to make the investment a success, as ...
Step down converter provides electromagnetic compatibility
With the MagI³C-VDMM (Variable Step Down MicroModule), Würth Elektronik eiSos expands its product series of power modules with high power density, very few external components and electromagnetic compatibility. The step down converter with variable output voltage is a particularly compact solution in a LGA-6EP package (dimensions 3.2x2.5x1.6mm).
Driver boosts runtime from batteries in portables and IoT devices
STMicroelectronics’ STSPIN233 is the industry’s first low-voltage motor driver suitable for both single-shunt and three-shunt brushless-motor driving integrating a 200mΩ 1.3Arms power stage, in a slim and compact 3mm x 3mm package. The STSPIN233 also has the industry’s lowest standby current, at less than 80nA.
GaN transistor is x20 smaller than silicon option
Efficient Power Conversion (EPC) claims that its 350V eGaN power transistor is 20 times smaller than the comparable silicon. This makes it suitable for use in multi-level converters, for EV charging, solar power inverters and motor drives.
Wireless power transfer technology continues to grow
As wireless power transfer technology continues to mature and user awareness increases, the reliability and robustness of these wireless charging systems continues to improve.
Combining small size and high performance with non-magnetic properties
Johanson Manufacturing branded Variable Inductors, from Knowles Precision Devices, combine small size and high performance with non-magnetic properties. Inductors and variable inductors are necessary elements of many RF products. They are used for matching and loading low noise amplifiers, power amplifiers and mixers, as well as for providing frequency- selective resonant circuits in variable-frequency oscillators.
Bicycling Power Meter offers next-gen nanotech
The new up and coming cycling brand iQ2 has developed an all-new, cutting edge Power Meter offering performance-improving benefits and advantages that, until now, have only been affordable to pro cyclists—and those with deep pockets. This new next-gen cycling tool not only offers vastly improved performance over existing Power Meter options, but does so with breakthrough pricing starting at $199 versus others costing $400 to $1000 or m...
Battery shredding equipment reduces UK environmental impact
The first fully functioning battery recycling plant in Scotland which can handle up to 12000 tonnes of battery waste every year, is extending its dismantling lines to prepare for the disassembly of an increasing number of electric vehicle (EV) batteries (Li-Ion), as the uptake of electric vehicles increases across the UK.
