Efficiency in power conversion circuits
by Steve Roberts, Recom A quick review shows the sources of inefficiencies in both linear and switching power supplies. Most engineers know that one reason switch-mode power supplies have become widely used is their high energy efficiency. But many engineers don’t know power supply technology well enough to explain the sources of switch-mode efficiency and […]
