SineFormer inverter output filter technology recently introduced by EPCOS is used for frequency converters and drives. In contrast to convention filter topology, the SineFormer simultaneously converts the phase-to-phase voltages into sinusoidal waveforms and thus minimizes the common mode current that can damage motor bearings. By suppressing common mode voltage peaks to … [Read more...]
Line of Small Shielded Chambers Targets Pre-Compliance Test Needs
A new line of small fully anechoic chambers from Netherlands-based Comtest meets a growing need for pre-compliance testing of small products. The chamber design is based on Comtest’s Pan-Shield shielding panels that provide high shielding effectiveness over a wide frequency range. Additional RF absorbers within the chamber prevent reflections from the metal walls that could … [Read more...]
National Semiconductor's New Amplifier Family have Integrated EMI Filters
National Semiconductor's New Amplifier Family have Integrated EMI Filters National Semiconductor Corp. has introduced three new operational amplifiers (op amps) with integrated electromagnetic interference (EMI) filters that maintain the accuracy of analog systems by reducing the effects of radio frequency (RF) interference. The LMV83x op amps deliver the industry's highest EMI … [Read more...]
Another Australian Physician Weighs in on Cell Phone Safety Debate
Regular readers of the eNews will recall that earlier this year we carried an article on Australian neurosurgeon Vini Khurana and his report Mobile Phones and Brain Tumors—A Public Health Concern. In short, Dr. Khurana warned that exposure to electromagnetic fields could be just as harmful as smoking and that there’s the possibility for dire health consequences for long term … [Read more...]
