This article is dedicated to Jim Williams who several years ago (2006) wrote an article in EDN regarding the need of a good lab apparatus to qualify the behavior of voltage regulators for compliance ...

The first major performance item to review is large-signal load-transient response performance. Here, a large-signal phrase is used in contrast to a small-signal. A small-signal transient literally ...

You use an active-load test circuit to ensure that a power supply for a microprocessor or for other digital loads supplies 100A transient currents. This active load can provide a dc load for a power ...

Performance under transient loads has become the most important specification of voltage regulators used to power a wide array of products whose current demands vary quickly during operation. Testing ...

The transient performance and frequency stability of hysteretic-based synchronous DC-DC converter ICs can be improved with ramp control and adaptive on-time techniques. The control method used in a ...

Editor's note: This article was first featured in the February 2003 issue of EC&M. It has been updated to reflect newer power quality instruments and updated standards. Today, many facilities have ...
