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 ...

Regardless of the system architecture, the circuit design, or the power levels involved, transient load current step testing is a critical aspect of power-system design, test, and verification.

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 ...

Second-stage output filters are often used to attenuate the output voltage ripple of a switching power supply. They can also isolate one load circuit from another. In this power tip, I will describe ...

ABSTRACT Pollutants are a major issue of diesel engines, with oxides of nitrogen (NOx) and airborne total particulate matter (TPM) of primary concern. Current emission standards rely on laboratory ...
