Fast, automatic and reliable characterization of
switching mode power devices
Today’s power supply designers are facing an increasing number of constraints in the
development of high-efficiency, low-cost power supplies. Cost-effective solutions used
to be the designer’s key target. Today, rising energy costs bring power supply efficiency
to the forefront. Additionally, other constraints such as design compactness, migration
to digital control, tighter voltage tolerances, and regulations for power quality and EMI
force the need for quick and reliable power supply testing. Increasing design constraints
translate into more time dedicated to power device measurement and analysis for
today’s power supply designers.
In spite of the increasing analysis capability offered by many oscilloscopes over recent
years, it is not uncommon to see designers perform measurements and characterization
manually. These measurements typically take a considerable amount of time to capture,
analyze, and report.
