Novel DC/DC Converters For High-Power Distributed Power Systems

Integrated Power Devices Simplify an Embedded Dc-dc Power Supply

A new class of integrated power devices has been developed to simplify embedded dc-dc power supply designs. The paper includes comparison with existing discrete/co-package solutions and a new methodology that has been developed in how integrated devices are being designed, specified, tested and qualified. The paper also details how treating integrated devices as power supply modules instead of ...
