Determination of the Ideal Power Inductor for Energy-Efficient Applications

Alexander Gerfer, Ranjith Bramanpalli, Jochen Baier, Würth Elektronik

Energy-efficient devices are important components for saving resources and protecting the environment. The more efficient the electronics, the longer the battery service life for mobile devices - and in large-scale industrial and server installations with thousands of loads, the energy requirement is markedly

Power inductors and peak-current handling capability

Nelson Garcia, Engineering Manager, Renco Electronics

As high-tech electronic products and their power supplies continue to shrink in size, design engineers should look closely at the peak-current handling capability of power inductors. Design engineers

Thermal design considerations for thin power MOSFETs

Ralf Walter, Application Engineer, Infineon Technologies AG

Thermal challenges accompany almost all advances in power-electronic designs. Load cases not covered under a datasheet's parameters are often particularly problematic. Each new MOSFET generation

String central inverter system

Frank Hinrichsen and Mark Ahmling, Wind and Sun Technologies

Planners of photovoltaic power plants are no longer bound to string inverter concepts if multiple MMP(maximum power point)-trackers are required. Central inverter systems are, today, standard for

Control and protection rests on measurement precision

Stéphane Rollier, Product and MarCom Manager, and Bernard Richard, Business Development Manager, LEM

Designers of solar power—photo-voltaic or PV—generating systems face some of the same problems as their counterparts in any other power-related technology: the need to constantly improve performance, reliability, longevity, and—above all—efficiency. As with any engineering endeavour, improved performance
