Secondary-side synchronous rectification boosts resonant converter efficiency
While secondary-side synchronous rectification in resonant half-bridge topology is not uncommon, its implementation has not been easy. A novel control scheme precisely turns on and off the secondary-side synchronous rectifier MOSFETs to achieve rectification that emulates a Schottky-diode rectifier, minimizing switching losses and optimizing conversion efficiency.
Smooth operators communicating for communications test
LXI and PXI instruments and related software provide the synchronization necessary for making complex measurements, and they enable test automation in the lab.
Industry standards lead push toward energy-efficient computing
Environmental concerns and rising energy costs are spurring industry and government groups to develop requirements for high-efficiency ac and dc power conversion, leading to energy-efficient servers. Meeting the newest specifications will demand knowledge of competing power-conversion topologies, components, and design.
PCB-layout techniques for gigasample ADCs
When a multilayer board operates at speeds greater than a few hundred megahertz, it's a challenge to maintain signals without mismatches, losses, distortion, or EMI. Follow these guidelines for PCB layout to preserve signal integrity and achieve high-speed performance.
