Whiteboard of the Week: LED Display Panel for Traffic Management

One of the latest Whiteboard Power Chains of the Week is a power system for an LED display panel that was developed by Marco La Ciacera, our technical sales engineer for Southern Europe. Here’s what he told us about this design.   Can you explain a little more about the application? The power chain was designed for a variable message sign (VMS), signs that can be placed in a wide range of places like highways, major road junctions, and urban arteries. Typically installed at the side or above the roadway, the VMS uses text...

White Paper Explains How ZVS Technology Enables Higher Power Throughput in Buck Regulators

January 28, 2014
By

The efficiency of conventional hard-switched niPOL regulators drops as the step-down ratio increases, and falls dramatically when required to accept a wide input range with step down ratios approaching 36:1. This means that designers have been forced to incorporate multiple converter stages, limiting the step-down ratio of each stage to maintain efficiency at acceptable levels.

High Density Power Solutions for Heavy Power Regulation

High Density Power  Solutions for Heavy Power Regulation

Vicor’s VI Chip PRM is a very efficient non-isolated regulator for high power applications, delivering up to 500 W from a single chip. It uses Zero Voltage Switching (ZVS) technology to  buck and boost a wide range of input voltages, providing a regulated, adjustable output voltage. In this post we see why the PRM improves and eases power system design, and give an overview of the internal topology behind its power density and efficiency.
