    Understanding radiation reports: the low down on particle LET

    There are high levels of radiation in space, primarily electrons, protons and heavier ions. When an energetic particle travels through matter (like silicon), it suffers numerous interactions that extract some of its kinetic energy. The energy lost ...

    Save PCB space and overcome point-of-load design complexity with PMBus modules

    Engineers face many difficult challenges when designing power supplies for industrial and communication systems. A typical system can include one or more field-programmable gate arrays (FPGAs), application-specific integrated circuits (ASICs), systems-on-chip (SoC), networking and communication processors, or other types of processors. Each processor typically requires complex power management of multiple rails (four...

    The power to innovate industrial design

    Ten years ago, after years of constant urging from colleagues and customers alike, I realigned my calendar and headed to my first ever Applied Power Electronics Conference (APEC). I will be on hand this week in Tampa, which I believe marks the event’s 32nd year. In reviewing my last decade of participation, I have two notable observations – one involving a great deal of change and the other, not so much. ...

    Rethink compute density with GaN

    According to a report published by the Lawrence Berkeley National Laboratory in 2016, data centers across the United States consumed a whopping 70 billion kWh of energy in 2014. It comes as no surprise that the industry is continuously looking for ways to increase power efficiency and density. Higher efficiency saves both electrical and major operational expenses such as cooling. It also enables operators to increase...

    How to enable high-accuracy CW Doppler through discrete, precision data converters

    Medical ultrasound is a noninvasive method of imaging the body’s internal structures (like organs) by transmitting high-frequency waves and measuring the reflections that occur at various boundaries within, such as between bone and muscle. Ther...

    Can a clock generator act as a jitter cleaner?

    I’m excited to have the opportunity to address clock generators and jitter cleaners. My goal is that after reading this post, you will not stereotype a clock generator as a device that can’t also perform jitter cleaning. I will discuss the difference between clock generators and jitter cleaners, cover some key points about phase-locked loops (PLLs), and discuss the performance characteristics of wide- and...

    Emerging industrial innovations using DMDs

    I had the privilege of representing Texas Instruments and chairing a conference titled “Emerging DMD-Based Systems and Applications” at SPIE Photonics West this year. Photonics West is a huge conference with over 20,000 attendees, 4,800 papers presented, 1,300 company exhibitions and three conference groupings (BIOS, LASE, and OPTO). I continue to be amazed at the creative applications being explored with...

    Know your gate driver

    I hope you’ve had a chance to watch our video series, “ Know Your Gate Driver .” Although often overlooked, gate drivers are responsible for a lot of the heavy lifting in systems like power supplies and motor-control systems. I like to think of a gate driver as a muscle ! The video series explains how while highlighting key gate-driver parameters. Topics range from negative-voltage handling and delay...

    Cool down your industrial system design with integrated data and power isolation

    Winters are getting shorter and temperatures are on the rise, and I think you’ll agree with me that overheating is never a good thing. Whether it’s human beings, equipment or pizza, you never want anything to be too hot. As the demands on industrial applications – such as factory automation and grid infrastructure equipment – increase, the need to add more features to the system increases as...

    Common challenges when choosing the auxiliary power supply for your Server PSU

    High-power converters used in server, telecom and industrial systems need auxiliary power supplies to support the housekeeping needs of the power-supply unit (PSU). Due to the ever-growing need for higher power density, these PSUs use an additional add-on card to support their auxiliary needs. An auxiliary power supply commonly powers the internal control electronics, voltage and current feedback sensing electronics...

    Selecting a bidirectional converter control scheme

    The 48V-12V dual-battery power system is becoming popular for mild hybrid electric vehicles . The vehicle’s dynamic operating conditions may require the transfer of electric power as high as 10kW back and forth between the two battery rails. Because of all sorts of operation scenarios in a moving vehicle, controlling the power flow needs in one direction or the other in real time can be a rather intricate task that...

    Interconnecting automotive 48V and 12V rails in dual-battery systems

    Electrification of the automotive industry is happening at an ever-increasing rate, driven largely by government standards on carbon dioxide (CO 2 ) emissions reduction. The European Union set a goal for new vehicles to emit only 95g/km of CO 2 by 2020. Other countries like China are setting similar regulations. To meet these standards, automotive manufacturers are moving toward mild hybrid electric vehicles , which use...

    LDO basics: dropout

    The quintessential characteristic of a low-dropout (LDO) linear voltage regulator has to be dropout. After all, that is the source of its name and acronym. At the most basic level, dropout describes the minimum delta between V IN and V OUT required for proper regulation. However, it quickly becomes more nuanced when you incorporate variables. Dropout, as you’ll see, is essential to obtaining efficient operation...

    Long range sensor-to-cloud: Connecting to Amazon Web Services with Sub-1 GHz-based devices

    Proven effective through many years of use in proprietary networks, bands within the Sub-1 GHz frequency enable long-range communication for applications such as connected door or window sensors, smoke alarms and metering. In addition to long-range, these radio waves can better penetrate walls and bend around obstacles while consuming very little power for operation. These attributes make Sub-1 GHz an optimal choice...

    Exploring high-voltage transmission – part 2, voltage-source converters

    The first installment in this two-part series covered line-commutated converters (LCCs). In this installment, I will discuss voltage-source converters (VSCs) and compare the two topologies. The VSC has become the preferred implementation for several reasons. VSCs have lower system costs because their stations are less complicated. VSCs enable a bidirectional flow of current, making it easier to reverse the direction...
