Why SiC Devices Are Ideal for Level 3 EV Charging Applications

On September 24, 2019 in All, Power, Wide Bandgap by Robert Huntley

Charging an EV can be a lengthy process, however, Level 3 “fast” DC charging techniques promise much faster charging capabilities that reduce charging times to minutes instead of hours. This efficiency relies on high-speed power conversion, for which new wide-bandgap technologies are well suited.

Achieving a Single Higher Voltage from a Dual-Output DC/DC Converter

On September 10, 2019 in All, Power by Robert Huntley

As applications use more sophisticated devices, the demand for more complex supply voltages increases. One viable approach to meeting the requirement for a higher voltage rail includes the use of a dual-output DC/DC converter. This blog explains how to integrate this type of converter into your designs.

Selecting a No-Opto Flyback DC/DC Converter for Space-Constrained Designs

On August 29, 2019 in All, Power by Robert Huntley

Traditionally, isolated DC/DC flyback converters used an optocoupler or a third transformer winding for line regulation. This led to design complexity, increased cost, and the need for more PCB space. Simplify your design with a no-opto flyback converter IC to regain PCB space and lower your BOM cost.

The Underlying Chemistry of Piezo Materials

On February 6, 2019 in All, Energy Harvesting, Power, Sensors by Liam Critchley

The electrical properties of both piezoelectric and piezoresistive materials change when subjected to mechanical deformation. Here, we show how and why these electrical changes are due to changes within the crystal structure at the atomic level and the chemistry involved with these changes.
