High voltage ICs give designers an advantage they can appreciate

High voltage ICs give designers an advantage they can appreciate
  It’s not easy being tasked with designing a 'better' DC/DC buck converter, which must transform a lightly regulated DC voltage into a tightly regulated source for motors, industrial equipment, and communications infrastructure; as always, the objective is higher efficiency, but without any penalty in size, complexity, or performance.

Current shunts enable accurate measurement of high currents

Current shunts enable accurate measurement of high currents
Manufacturer of power and precision resistors, Riedon, has expanded its portfolio of precision current shunts to provide what it claims to be one of the broadest range of current ratings available today. Responding to increases in the output levels from renewable energy sources, higher capacity batteries that require shorter charging times, and the widespread electrification of heavy industry, Riedon has designed its shunt resistors to enable accurate measurement and monitoring of high currents.
