The quest for energy efficiency has focused attention on those components of the power electronics that can connect hundreds of volts and amps in inverters with exceptional efficiency. We are talking about modern power switches – IGBTs and SIC-FETs – and how the voltage supplied to the respective gate drivers
High-voltage IGBT-modules usually consist of two types of IC, an IGBT for the transistor and a diode for the freewheeling functionality. A device that combines both functions in a single die is known as a reverse conducting IGBT (RC-IGBT). These modules exhibit a lower thermal resistance when compared to an
Multi-Layer Ceramic Capacitors (MLCC) in chipscale surface-mount packages are widely used in electronics for consumer, medical, industrial, automotive, and other applications. Their combination of affordability, compatibility with high-volume assembly, high capacitance values within small dimensions, and high
Equipment designs increasingly utilize advanced MCU, DSP and FPGA devices to deliver the functionality and performance demanded of them. With this sophistication comes the challenge of providing the multiple power rails these devices require. The use of carefully chosen power modules can significantly ease this
Here we’ll look at how a rugged and flexible control can be rapidly implemented using an 8-bit microcontroller with analog blocks. For many custom power supplies, this provides an optimum combination of noise immunity, high performance, short development time, and digital flexibility.
People don’t think about engineers much, and in general engineers are looked upon in a positive light. Unless something goes wrong with something. In the marketplace, engineering is usually the first direction people point fingers when problems occur in a product.

Millions of customers and tourists across Nevada are benefitting from improvements in the quality and continuity of their electrical supply, thanks to a technology upgrade made by their local utility company. NV Energy selected Aclara's grid monitoring platform to retrofit aging substations, distribution feeders
Associate Professor Xudong Wang holds a prototype of the researchers’ energy harvesting technology, which uses wood pulp and harnesses nanofibers. The technology could be incorporated into flooring and convert footsteps on the flooring into usable electricity
Flooring can be made from any number of sustainable materials, making it, generally, an eco-friendly feature in homes and businesses alike.
Now, however, flooring could be even more “green,” thanks to an inexpensive, simple method developed by University of Wisconsin–Madison materials engineers

Like most municipal infrastructures, any technology used must be accessable and scalable. gridComm transforms urban streetlights into dynamic, resource-efficient platforms by using proprietary
The Baker, Benthall Bridge, and Turkey Creek Solar Parks represent a combined investment of more than $45 million
Ecoplexus, a leading developer of solar photovoltaic (PV) projects, announced today that it has begun construction on three more ground-mounted installations in North Carolina. The Baker, Benthall Bridge, and Turkey Creek Solar Parks represent a combined investment of more than $45 million.
Envision Solar International, a leading renewable energy and EV charging product company, announced that New York State has issued a purchase order for the Company's EV ARC product.
Envision Solar has previously delivered the EV ARC product to New York City, but this is the first purchase order from
Navigant Research's third quarter report sees a growing role for residential installations
Critics called 2015 a "banner year" for energy storage.
Now after a year of unprecedented growth, energy storage could be poised to best that performance, according to Navigant Research’s third quarter energy storage tracker.
“The North American market this year definitely
A key consideration for wireless sensor nodes that will populate the Industrial Internet of Things (IIoT) is battery lifetime. The sensor nodes, in many applications, will need to be installed in locations that are difficult to reach and, consequently, service. Because it is too costly and difficult to run power
Oftentimes, designers of digital cameras, mobile devices and other consumer electronics choose to power their device from two, series-stacked, Lithium-Ion (Li-Ion) batteries, yet still desire the capability to charge from a 5-V universal serial bus (USB) port. Boosting a 5-V USB input to charge two series-stacked
The extra wide input PQB50U-72S and the ultra-high power density PFB600W-110S
Powerbox, a leading force for 4 decades in optimizing power solutions for demanding applications, introduces two new board mounted DC/DC converters to power industrial and railway applications; the extra wide input PQB50U-72S and the ultra-high power density PFB600W-110S. With an unprecedented extra wide input
The energy landscape has changed
The energy landscape has changed with most countries achieving a more diversified energy mix as well as a growth in community ownerships and an evolution of micro grids. A new report launched at the 23rd World Energy Congress on 12 October reveals that the unexpectedly high growth in the renewable energies market,
Having a good grasp of how measurement tools actually operate can provide valuable insight into how test methods can be improved. Setups can subsequently be made simpler and more effective, plus test performance parameters can be significantly raised. This is true for any sphere of technology that requires the
LGA package technology can deliver important advantages for the high-performance Point-Of-Load converters needed to feed power-hungry, fast-reacting data centers and network infrastructure. As the power demands of high-performance Cloud and telecom computing systems continue to increase, converter modules that
Continuing the old story-telling tone which began the issue, I would like to point your attention to the centuries-old proverb “For want of a nail” which describes a chain of events and their consequences from a small error snowballing into catastrophe. There are many lessons to draw from this, from the
Here we’ll explore the analytical transfer function for the tightly-coupled Sepic converter. It is shown that the control-to-output function is just second-order, not fourth-order like the conventional Sepic converter . The coupling capacitor of the converter has no effect on the control, and it can be

The role of an uninterruptible power supply (UPS) is simple in concept: provide a temporary power bridge to support the load between the loss of the utility and the transfer to diesel generators. Even though the task is easy to define, the best way to achieve the goal is often clouded in obscurity as the benefits
EMC problems in frequency converters occur not only at the input, but also at the output. To ensure reliable elimination of any kind of interference at the output as well, companies like TDK, for example, offer a wide range of EPCOS filters and reactors.
Frequency converters are used for regulating
Automated factories employ sensors and I/O modules to control their industrial processes. As they increase in sophistication and shrink in size, they are enabling the fourth industrial revolution, dubbed Industry 4.0. A single module (see Figure 1) can have up to 64 channels, and a typical factory floor may
Industry 4.0, the latest industrial revolution, is changing the way manufacturing organizations think about production. The aim of Industry 4.0 is to make manufacturing more flexible and responsive to customer needs, providing the ability to make small batches that are tailored to individual customers.
