Introduction
Having trouble obtaining consistent results from your Double-Pulse Test (DPT) setup? You are not alone. As the switching frequency of switch-mode power converters increase into the MHz range, rise/fall times are dropping to 10ns or even single digits of nanoseconds. It is no longer possible to design & measure power converter performance without considering high frequency effects. This article discusses DPT fixture design to obtain repeatable and reliable results from your DPT setup.
