MLCC and Tantalum Electrolytic Capacitor Interchangeability in High Capacitance Applications Chris Reynolds – AVX Corporation  Over the years, ceramic capacitors have been used interchangeably with tantalum in many digital applications, class II ceramics being the one electrostatic technology that can achieve the high capacitance values typically associated with electrolytic capacitors. We are currently at a point where more electrolytic designs are being re-considered for applications that had switched to class II ceramic in recent years. While most applications are amenable to such interchangeability, some parametric factors arise due to the differences in technology, so these need to be taken into consideration. This paper discusses the differences between electrostatic and electrolytic technologies, explaining the origin and effects of temperature and voltage coefficients, piezo and noise effects in class II ceramics, and polarity and ESR in solid tantalum electrolytic capacitors.

Realizing a Transformerless Future Bud Courville It’s an all-too familiar sight in today’s homes and businesses: a tangle of cords emerging from behind a console, desk or conference table, connected to several large, bulky power supplies. TVs, DVD players, set-top boxes, sound bars, digital media devices, monitors, printers, routers, laptops…the list of devices connected to these power supplies is seemingly endless. It doesn’t have to be this way, according to fabless power semiconductor company Helix Semiconductors. Traditional power supplies are built around century-old methods. Transformers are the culprit here: they are big, cumbersome, heavy, inefficient, and inflexible, and they usually dictate the size and form factor of a power supply. Getting the maximum amount of power in the smallest space possible is the key to a new way of powering the world, and proprietary technology from Helix Semiconductors has accomplished exactly that. Come listen to our story and learn about how our MxC 200 and MxC 300 family of products enable a transformerless future. Helix Semiconductors Wednesday, March 20, 2019-11:15AM-11:45AM

The LV100 and HV100 New Standard Modules for High Power Applications Eric R. Motto,  Chief Engineer – Power Semiconductor Applications This presentation will introduce the LV100 and HV100 new industry standard module packages for high power applications.  Existing high power single modules in common 130mm x 140mm and 190mm x 140mm packages introduce a large stray inductance when series connected to form an inverter leg.  This large inductance makes higher frequency operation and parallel connection challenging.  Similarly, common large dual modules in 89mm x 250mm and 89mm x 172mm packages have significant internal asymmetries that cause undesirable current and temperature imbalance when the switching speed is increased.  These problems become more pronounced with state of the art IGBT chips like Mitsubishi’s 7th generation CSTBTTM (III) and practically unmanageable with SiC MOSFETs.  Elimination of these limitations is the primary motivation for development of new high power modules having low and symmetric internal inductance with an optimized power terminal layout.  This presentation will outline the characteristics, features, performance and line-up of these new modules.

Death to Heatsinks Doug Bailey- Vice President of Marketing Examine most consumer product power supplies and you will find at least one heatsink. Generally, they are made out of a piece of extruded or stamped copper or aluminum. The heatsink’s job is to couple wasted energy into the ambient environment, where it can’t do any harm. Think about the concept of “wasted energy”. Who says it’s waste? Who says that it’s OK to dispose of it and why is it wasted in the first place? In an age where advanced materials and sophisticated controller techniques abound, isn’t it time for a rethink? Consider instead that the existence of a heatsink in a product represents a quantum of failure: Failure of our society to efficiently manage our energy resources, failure of our designers to specify products that are compact, light and unobtrusive and a failure of project definition experts to leverage the technologies that are readily available. As an industry, we are continuously tempted to sacrifice energy, product utility and cost of ownership for unit cheapness, passing the electricity bills onto the end user and wasting resources. This presentation is an unabashedly partisan attack on the practice of heatsinking, along with a review of the materials and techniques that we can, as engineers, leverage now and in the future to make better products. Death to Heatsinks!!! Power Integrations Wednesday, March 20, 2019-10:30AM-11:00AM

HIL Testing and Controls for Power Electronics Made Easy with Speedgoat Real-Time Solutions Daniel Kraehenbuehl Simulink Real-Time and HDL Coder, together with Speedgoat real-time systems, create a complete and seamless integrated real-time software and hardware environment for rapid control prototyping (RCP) and hardware-in-the-loop (HIL) simulation. Simulink Real-Time provides a high-performance host-target prototyping environment that enables you to connect your Simulink/Simscape models to physical systems either running C code on a CPU and/or HDL code on an FPGA. Speedgoat offers a wide band of optimized hardware sufficiently equipped with high speed analog and digital inputs and outputs. Verifying and testing the control hardware with its embedded software against a virtual prototype of the controlled system using deterministic and equivalent real-time simulation is a proven step before proceeding to prototype hardware testing. In HIL testing, power electronics, power stages, sources, loads, and even a grid network are simulated in system-level models running on dedicated real-time test systems. The system lets you perform initial testing of embedded software without risking damage to hardware prototypes and develop a high degree of confidence that your software will perform its intended functions. Advances are being made to real-time test hardware through the incorporation of FPGAs, for high speed I/O and for running the simulation, the latter presenting a new challenge of programming over the more common use of C code on a microprocessor.

Flexible Architectures to Efficiently Convert from 48V to Intermediate Bus or Directly to POL Paolo Sandri 48V DC bus power distribution poses challenges on conversion efficiency, power density and total BOM optimization. ST offers a rich set of architectures to better fit, virtually, any need when converting from 48V to either an intermediate bus or directly to POL.  The architectures for the intermediate bus can either provide a regulated output or an unregulated one. The 48V direct conversion architectures delivers power directly to the Digital ASIC, whose cores typically requires several hundred Watts and other key challenges needs to be addressed such as the compliance with the specific ASIC power needs with a certain degree of sophistication in term of accuracy and mode of operations.

OPB9000 and Adaptable Sensors: Trends, Challenges and Developments Sergey Komarov Modern day sensors applications in portable medical devices, wearables, appliances, drones and autonomous vehicles pose new challenges for product designers and sensors developers. While the traditional purpose of optical sensors as motion or position transducers for non-contacting object sensing fundamentally has not changed, the variety of environments in which they operate and demand for portability in a data driven world place new requirements for sensors to become highly integrated and dynamically adaptable.  The OPB9000 reflective optical sensor from TT Electronics is one such device. It integrates an infrared (IR) emitter and a photodetector in one package, along with the analogue front-end circuitry, on-chip processing, and a digital interface in a surface-mount package of 4.0 × 2.2 × 1.5 mm. The circuitry is encapsulated in industrial resin, making it robust and able to operate at temperatures from –40 to +85 °C. In this session we will review the main trends, challenges and developments associated with adoptable sensors and their implementation in OPB9000. TT Electronics Tuesday, March 19, 2019-3:00PM-3:30PM

Challenges of Magnetic Component Core and Copper Loss Measurement Weyman Lundquist Isolation of magnetic core and winding loss in a transformer or inductor from small signal measurements can prove a challenging task. The device under test must be evaluated before performing a test, to discern if it is in a range where it can be accurately measured, or if simulation is a better choice for estimating loss. If a small signal measurement is chosen to estimate loss, the results must be interpreted carefully. In this talk, we present measurement ranges in which winding and core loss can be extracted from a small signal impedance analyzer measurement, and a method for doing so when extraction is feasible.

Avoid Designing Custom Magnetics by using REDEXPERT George Slama Designing your own custom magnetics may seem like a good idea at first. After all, you’ll get exactly what you want. But will you? Consider the time and effort that first goes into some type of design and then into procuring the necessary cores, bobbins, wire and later into actually winding and gapping the core. This also requires equipment since only the simplest inductors can be made by hand. The best performing magnetics generally use techniques (e.g. rectangular wire wound on edge) and materials (e.g. pressed composites) not available outside of manufacturing facilities. This session will show you why it makes sense to use standard magnetic components and how to take advantage of the wealth of performance information available to help verify your design. Based on actual testing, REDEXPERT gives you access to the world’s most accurate ac loss measurements for inductors. Discover the broad of range of solutions available for next day delivery. Learn how to easily and quickly select the right inductor, flyback transformer or wireless power transfer coil for your application. Wurth Electronics Tuesday, March 19, 2019- 1:30PM-2:00PM
