The design of a switching power supply has always been considered a blend of magic and art by every engineer that designs one for the first time. Fortunately, today the market offers different tools ...
In Power Tip #3, we discussed how the source impedance of an input filter can turn resistive, and how it can interact with the negative input impedance of a switching regulator. At worst case, these ...
Decreased system reliability due to overloaded power supplies is a common engineering challenge. In this Q&A-style article submitted by Allied Electronic & Automation, David Norton, technical ...
A follow-up to the article “Design a PFC Resonant Coupled Inductor That Doesn’t Distort Power Factor” (July 2015) described the design of the resonant inductor. This article describes how ...
Noise is a constant problem in power-supply design. While there are FCC limits on the electromagnetic interference (EMI) radiating out into the air as well as the conducted noise that your design ...
ABSOPULSE Electronics has recently released the PFC 319-D4 Series of IP66-rated AC-DC power supplies with active power factor correction (PFC). The units are designed for heavy-duty applications that ...
