DC/DC converters come in two versions

DC/DC converters come in two versions
A series of compact 15W high performance DC-DC converters from CTC are available at Luso Electronics. They offer outputs ranging from 3.3V up to 15V, operation over a wide temperature range and power efficiencies of up 87%. Encased in nickel plated copper, the new RoHS compliant converters are available in two versions: the PC15WR offers a 2:1 wide input voltage range and the PC15WR4 variant provides a 4:1 wide input voltage range.

Edible batteries could power ingestible medical devices

Edible batteries could power ingestible medical devices
Non-toxic, edible batteries could one day power ingestible devices for diagnosing and treating disease. One team reports progress toward that goal with their batteries made with melanin pigments, naturally found in the skin, hair and eyes. The researchers will present their work at the 252nd National Meeting & Exposition of the American Chemical Society (ACS).

A smaller and faster IPM with CIP topology

A smaller and faster IPM with CIP topology
The launch of a new, deeply integrated Intelligent Power Module for 600V applications has been announced by Vincotech, a supplier of module-based solutions for power electronics. The flowIPM 1B CIP 600 V features the powerful combination of a high-speed F5 IGBT with the switching performance of a MOSFET and a silicon carbide boost diode in the PFC circuit optimised for frequencies up to 150kHz.

UK battery sector investigated and explained

UK battery sector investigated and explained
Although many people believe that Thomas Edison is responsible for the first light bulb, it was in fact British chemist Joseph Swan who invented the light bulb. It was Swan who first developed the incandescent bulb and lit his house with electricity. This is one of many great contributions that the UK has made to the field of science and technology, with the industry showing little signs of slowing down.
