CIE - Lighthouse in Electronics at the Danish/German Border
A unique public-private partnership was created last summer when Danfoss, Linak, the Bitten and Mads Clausen's Foundation, the Region of Southern Denmark, Sønderborg Municipality and SDU joined forces and established the Centre for Industrial Electronics (CIE) as part of the section SDU Electrical Engineering. Altogether, the six partners invest more than 30 million € in order to address the shortage of engineers which enterprises of the region are facing. A completely new building will be erected, connected to the existing university building with a glass bridge and accommodating laboratories and test facilities for the new centre.

Infineon Reported Results for the Second Quarter of the 2018 Fiscal Year
"Infineon continues to grow profitably," stated Dr. Reinhard Ploss, CEO of Infineon. "Our growth is broadly based: Solutions for the entire range of drivetrain systems for all types of electric vehicles, including 48-volt systems, high-speed trains and renewable power generation. In addition, we are seeing growing demand for data center power supplies for artificial intelligence. Our order books are bulging. We therefore are very confident that we will achieve our revenue targets for the 2018 fiscal year. Compared to the previous year's March quarter, the average US dollar exchange rate against the euro fell by around 16 percent in the three-month period to 31 March 2018. Despite headwinds from the US dollar and rising material prices, we expect to achieve our targeted Segment Result Margin of 17 percent again in the 2018 fiscal year. This demonstrates the robustness of our business model," continued Dr. Reinhard Ploss.

Designing Custom Inductors with ONE Design Equation

In the last article of this series, I introduced one equation that matters for inductor design. This is the equation that you will use when you are creating a custom design from scratch. Please note that we are talking about the design of an inductor, NOT the analysis process. Mathematical structure analysis can be quite involved and is a popular subject for PhD dissertations.

Renewable Energy
Making Single-Phase Solar Inverters Smaller, Cheaper & Safer

New technologies allow photo-voltaic (PV) inverters to switch at ever higher frequencies and consequently they are becoming much smaller and lighter. International competition and the move away from subsidies for new installations mean that there is strong pressure on their cost. The current transducers used in PV inverters must follow these trends: they must have a reduced footprint while having equivalent or improved performance at lower cost, compared to the transducers they replace.

Making the Most of Three-Level NPC Topology

Three-level NPC topologies are popular choices for solar, UPS and energy storage applications these days. The unique requirements of each application play a key role when selecting the components for a power module. A universal standard chipset is not always the best solution. This article looks at two chipset combinations to highlight the importance of understanding how the target parameters affect the selection of chips and modules.

Handling Late Changes in Power System Designs

Providing power to today's electronic systems designs has become a complex and challenging exercise. Stable power, efficiently delivered at the correct levels, is the bedrock on which all other performance parameters rest. The pursuit of ever-more demanding specifications and ever-lower power losses has come to be seen as requiring more specialised expertise. Those working in the power area see some serious problems ahead, and anticipate a need for more engineering resources, for better-qualified and more-experienced power system engineers – and for new approaches to architecting, and implementing the power system design.

Technology
DCM 1000X - Designed to Meet the Future SiC Demand of Electric Vehicle Drive Trains

Global warming and pollution as well as international carbon emission targets initiated a process to reduce car emissions. The automotive industry pushes to improve fuel efficiency and reduce emissions, also by increasing the vehicle electrification. Increasing global demand for BHEV, BEV vehicles and new drive train designs causes automotive manufacturers to evaluate suitable power electronic technology in their current and future designs. Automotive manufacturers constantly seek improved overall performance: higher conversion efficiency, reduced cost, lower weight, higher power density.

Driver ICs
Optimisation of dV/dt – Losses Trade Off Using Switchable Gate Resistance

System-level effects in power converters are often caused or constrained by behaviour of the power semiconductor devices, for example high dV/dt from modern IGBTs. Bulky and lossy dV/dt filters are often required in high-power converters to limit the voltage stress on insulation of wound components, e.g. motors. By taking advantage of real-time bi-directional communication over the fibre-optic link, Amantys gate drives reduce the need for dV/dt filtering through intelligent selection of gate resistance, thus enhancing the overall system performance and power density.

Transistors
A Novel Circuit Topology for Turning a 'Normally On' GaN Transistor into 'Normally Off' that Can be Driven by Popular Drivers

In the past year, it has become clear that Gallium Nitride (GaN) power transistors have been successfully launched in end user's products, as has been reported by the various GaN device manufacturers. Examples include Transphorm products in Corsair's AX1600i Power Supply Unit (PSU) and Bel Power Solution's TET3000-12-069RA power supply, and Infineon products in Eltek's Flatpack2 SHE power conversion module. The system performance and cost benefits in, for instance, a Totem Pole Power Factor Correction (PFC) in high-end AC/DC power supplies (such as is the case in the Corsair and Bel Power Solutions' products) are so significant that GaN transistors are clearly destined to replace the incumbent Si MOSFET transistors.

I2C Controllable EZBuck Regulator
Alpha and Omega Semiconductor Limited introduced and new family of EZBuck regulators featuring I2C control. The first two members of the family are the 4A AOZ2231CQI-01 and the 8A AOZ2233CQI-02. The new devices provide a compact, efficient power converter solution for next-generation chipsets and FPGAs used in high-end TVs, set-top boxes, data storage systems, servers and other embedded systems. Next generation microprocessors and SoCs often use dynamic voltage scaling to reduce power dissipation and improve system performance. Implementing dynamic voltage scaling in a DC/DC converter often requires several external components.

The Smallest of its Kind in Composite Technology
With the BVF, Isabellenhütte Heusler GmbH and Co. KG has developed a precision resistor that not only impresses with its unique overall size 1213 (3.1 mm x 3.3 mm), but also with its extremely high load capacity and precision in use. Smaller electrically-operated applications in particular benefit from the properties of the high-performance component that Isabellenhütte has now included in its series repertoire. With its small overall size, the BVF is currently unique on the market. The temperature coefficient of the BVF precision resistor is just under 70 ppm/K. The thermal resistance is also extremely low at 10 K/W. This results in the high load capacity of the BVF of 3 watts at up to a temperature of 145°C at the contact point.
