Today’s power conversion and power management applications demand compact yet robust power switching circuitry that supports high-voltage, high-frequency operation with the minimum of losses from the smallest possible PCB area.
By definition, the choice of MOSFET technology has a significant impact

The first modern wave of rapid human development, also known as the first industrial revolution, began in the middle of the 18th century. The development of devices that could be used to magnify a human’s capabilities immediately changed the face of the planet, impacting everything from agriculture
Many fields of research focus on achieving a combination of more powerful batteries and devices that consume less and less energy. However, Moore's law does not apply to batteries.
The performance and component density of processors and memory chips double approximately every 18 months. Gordon E.
The distributed intelligence that has been the defining characteristic of the Smart Grid can do more than enable smart homes and help utilities distribute power more efficiently. These two well-known advantages will be enhanced by two revolutionary changes at the edge of the power grid.
Energy harvesting has been around for a very long time. I still remember my 1980s pocket calculator with a solar cell powering the computing unit as well as the LCD display. But even much before that, usable energy was harvested in the early days of the electrical revolution with putting generators on river
A niche market only a few years ago, the solar photovoltaic (PV) industry is now becoming a mainstream electricity provider, and changing the way the world is powered. Following a difficult period of industry consolidation and economic crisis, PV installations saw another record year in 2013, with more than
There is near-consensus in the UK that smart grids and smart meters will substantially advance the way energy networks operate in the coming years. According to a recent report, more than two-thirds of utilities executives expect the benefits of the smart grid to actually be greater than the industry’s original
System architects of embedded systems, networking, and datacom equipment are constantly being pushed to increase the data throughput and performance of their systems as well as add functionality and features. At the same time, pressure is being applied to decrease the system’s overall power consumption. For
Did you know that every 10°C rise in ambient temperature reduces every component’s lifetime by 50%? That power supplies with drop-offs or variances can lead to premature failures and even completely fried parts in your system? Indeed, most agree that power-intensive applications need, and really must have,
We thought it would be helpful to assemble a top five list of the most common mistakes or “don’ts” that occur during the design of efficient power systems – and how to avoid them. This information comes from our observations and yes, some of our own experiences during Electrocube’s 50-plus years in
New carbon emission targets are driving significant changes around how electricity is generated, transported and consumed in the United Kingdom. With the increase in small-scale generation technology onto the network, DNO's are met with great challenges to facilitate a future low carbon network.
As power levels are increased and output voltages drop, it is common to have just a few turns in the windings of inductors and transformers. When this happens, standard round wires are usually not the best choice for building magnetic structures, and foil is often used. With a foil winding, the width of the

GaN material offers orders of magnitude improvement in switching and conduction performance and, when produced on GaN-on-Silicon substrates, can reduce power system costs. Only diamond power semiconductors have been proposed as a superior material system to GaN, but the consensus is that we are decades

There has been a tremendous amount of buzz around the recent unveiling of Elon Musk’s Tesla Powerwall, and even if the product does not completely live up to the hype it has already changed the debate on power management in the grid. Once focused on grid-level solutions, the discussion of energy storage in
The five winning Catalyst prize competitors pose with their award checks at Demo Day in San Francisco
Five solar start-up companies were named winners at SunShot Catalyst prize competition Demo Day on May 14 in San Francisco. The winners -- Gridmates, PVComplete, Savenia Solar Ratings, Solar Site Design, and UtilityAPI -- each took home $30,000 prizes to help advance their early-stage solutions towards commercialization.
