Power Supply in Inductor

Posted on 06 February 2015

      Inductor and packaging to optimize the POL Point of load regulators (POL) are very widely used in distributed power systems to deliver the final voltage required by the load, particularly for high performance ICs and ASICs. In most cases, these POLs utilize the Buck Converter switching topology to achieve high density and [...]

Applying Power Circulation Theory to More Accurately Measure Power Loss and Efficiency

Posted on 26 January 2015

      The race is on to push efficiency in power conversion beyond 99%. It is a contest with innovative new topologies running neck-on-neck with standard half-bridge solutions featuring SiC and GaN semiconductors. A wide range of applications requires bidirectional power conversion, and it has to be ultra efficient for everything from solar inverters [...]
