White Paper Explains How to Reduce Power System Size by Eliminating Bulk Capacitance

Although the need is most acute when designing power systems for applications such as aerospace, most systems benefit from smaller and lighter electronics. Bulk capacitance can represent a large proportion of the size and weight of a power chain, but engineers can eliminate it. You can find out more by completing e the form below to download Build Small, Lighter Power Systems by Eliminating Bulk Capacitance.

White Paper Describes How Eliminating Isolation Improves Performance of 48 V Power Systems

The telecommunications industry has traditionally used positive-referenced DC power distribution to reduce the chance of copper wiring corroding. Modern systems, however, often use active cathodic protection, eliminating the need for a positive-referenced power system.

White Paper: A Novel Approach to Industrial Rectifier Systems

AC-DC converters for industrial applications have been relying on double-stage architecture for quite a long time. A non-isolated, single- or three-phase, single- or multi-level stage typically feeds an isolated DC-DC stage, with capacitors between the two stages providing the necessary energy storage. The need for high efficiency and high density has determined the evolution of distributed power systems toward architectures that employ optimized power components. Among those power components, fixed-ratio bus converters have been developed to provide state-of-the-art performance, including components capable of 300-400V DC input that provide isolated, Safety-Extra-Low-Voltage (SELV) output. This paper,...
