Four standard models operate
Motor manufacturers are in a race to switch to more energy-efficient technologies to help countries reduce greenhouse gas emissions, as part of a global strategy to combat climate change. While many motor makers look to substitute more iron or copper in their induction motor product lines, or switch to other
Sales of hybrid cars in the USA collapsed from 3.2% of car sales in 2013 to under 2% in 2015 as Americans responded to the sharply reduced oil price. However the oil price will recover eventually so commentary that it heralds the death of hybrid vehicles is wide of the mark. Indeed hybrid car sales outside the

Jonah Teeter-Balin of AeroVironment
In this PSDcast Jonah Teeter-Balin of AeroVironment, an alternate-energy solutions creator, talks to Alix Paultre of Power Systems Design about his observations on the developing edge of energy-management tech. He talks about the state of the industry and his recent observations from the recent Consumer
PLS Programmierbare Logik & Systeme has now introduced version 4.6.1 of its Universal Debug Engine (UDE) including a specifically optimized testing and debugging environment for MPC5746R high end multi-core controller – the newest member of NXP’s Power Architecture family.
The high performance
LED technology has developed over recent years, and is now the obvious choice for many applications from energy-efficiency architectural lighting to outdoor displays. These applications tend to vary considerably, each requiring a different number, type, color and configuration of the LEDs, which means that driver
LEDs are increasingly used in 24VAC and 12VAC lighting systems as a robust, energy efficient and high performance alternative to halogen lamps. Power converters that drive the LEDs should have a high power factor (above 90% in order to meet generally-accepted green standards), should be efficient, use a minimal
Transformers can often provide an inexpensive solution for a variety of applications. The purpose of the transformer is to isolate the secondary side of the circuit from the primary power source, transfer power efficiently from the electrical source to the target load and protect users from hazards like electric
An effective method for filtering high-frequency power supply noise and cleanly sharing similar voltage supply rails (i.e. analog and digital rails for mixed-signal ICs) while preserving high-frequency isolation between the shared rails is the use of ferrite beads. A ferrite bead is a passive device that
It is no longer contentious to say that the future of land, water and air vehicles is to be more and more electric. The detail of how this is being achieved is rich and varied and it revolves around the electric motor and its variants far more than the more-discussed battery. By definition, an electric vehicle
The desire for ever higher image quality has seen frame rates in high-end televisions increase to 240 frames per second (fps) simply to ensure that the fast moving action in sports programs or movies does not suffer from smearing or multiple images. Display panels for PCs similarly need to support high frame
In the third part of this series, we’ll see how Dr. Fred Lee’s analysis of current-mode control resulted in a high modulator gain, and also look at the consequences of this gain on current-loop predictions.
