Measuring Power Loss in Switched Mode Power Supplies. LeCroy Application Brief No. LAB 438 Power Device Analysis Measuring Power Loss in Switched Mode Power Supplies Design goals for switched mode power supplies include designing more efficient power supplies that effectively reduce the size and costs of those supplies. Having tools that provide more insight into these cir- cuits supports these goals, as well as providing a designer with more con- fidence in power supply reliability under all operating conditions. One of the ways to improve the ef- ficiency of your designs is to reduce the power losses within the circuit. LeCroy's PMA2 Power Measure Analysis Software, which runs on X-Stream digital oscilloscopes, provides exceptional ability to measure and analyze the operating ……
