Cognitive Power Electronics 4.0 by Fraunhofer IISB

Cognitive Power Electronics 4.0 by Fraunhofer IISBPower electronic devices are at the very heart of every system, application and production machine in industry, energy management, building appliances, mobility, and more.

Right within the power electronic devices, electrical parameters are continuously available that indirectly characterize the current condition of an application or machine (e.g., energy grid, production machine, battery, motor). Up to now, those data are partially used to monitor the electronics in itself, but not yet for monitoring and optimization of the overall system.

With Cognitive Power Electronics 4.0, existing power electronic devices are augmented by “intelligence”: additionally embedded electronics collect the electrical parameters and do a preprocessing. Where applicable, external sensors are added as additional data source. The following step is of high importance: the identification and validation of correlations between the collected data and the behavior of the overall system or parts of it. The transfer of the found correlations into algorithms then allows the actual construction of the intelligent power electronics, capable of model-based decisions to realize smart systems.

Application in component analysis

Complex power electronic systems require highly reliable components that interact smoothly. To ensure highest quality and to characterize the dynamic behavior of components, test specimens are electrically stimulated in order to provoke a measurable system response, which allows the derivation of relevant parameters.

The application of Cognitive Power Electronics 4.0 to this scenario allows it to go beyond state-of-the-art oscilloscope-based analysis: A new instrument was developed that uses artificially generated noise signals to fully characterise power electronic components in the frequency range. This allows the measurement of individual devices as well as system networks in real time at high currents and under voltages up to 1000 volts. By means of a special evaluation software, characteristic parameters and dynamic behavior can be determined very accurately.

Application in vacuum systems

In semiconductor manufacturing, many processes rely on sophisticated vacuum systems. The interaction between process equipment and vacuum system may be quite complex: e.g., in deposition processes, the vacuum system is contaminated from the running process.

The application of Cognitive Power Electronics 4.0 to this scenario allows the continuous collection and visualization of the electrical parameters from the power electronics inside the vacuum system, providing 100% real-time facility state monitoring to the process engineers. Beyond that, a machine-learning algorithm was trained to predict the rest of useful life of the vacuum system until contamination gets critical. Based on this prediction, safety is improved and maintenance actions can be planned in-line with upcoming processing schedules.

Application in arc detection

The ongoing electrification of automobile auxiliaries imposes increasing power demands on the electric energy network. To reach these demands at reasonably low currents, an increasing number of 48 V loads is currently finding its way into vehicles. Opposed to the traditional 12 V energy networks, arc faults can occur in 48 V DC networks. These arc faults must be detected and eliminated before they can cause hazardous damage.

The application of Cognitive Power Electronics 4.0 to this scenario allows integrating arc detection functionality into electronic power distribution boxes: The load current is permanently monitored by the existing sensors of the power distribution box. A recurrent artificial neural network that was trained to detect the current frequency patterns of arc faults is executed in real-time by an FPGA. Once an arc fault occurs, the power distribution box can thus detect and safely eliminate it by disconnecting the respective load path from the power source.

Implementation scenarios for Cognitive Power Electronics 4.0

Actual implementations of Cognitive Power Electronics 4.0 may start modest by merely collecting and fusing data and providing it to other systems (“Power as a Sensor”). In more complex applications, Cognitive Power Electronics 4.0 analyses the collected data onboard and either monitors the overall system (“Power as a Monitor”), or takes action in system control (“Power as a Brain”). Finally, systems with embedded Cognitive Power Electronics 4.0 can be connected with each other or with cloud systems (“Power as a Network”) and offer flexible and adaptive functionality (“Power as a Service”).

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...

Im Focus: World record: Fastest 3-D tomographic images at BESSY II

The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.

Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...

Im Focus: A molecular switch may serve as new target point for cancer and diabetes therapies

If certain signaling cascades are misregulated, diseases like cancer, obesity and diabetes may occur. A mechanism recently discovered by scientists at the Leibniz- Forschungsinstitut für Molekulare Pharmakologie (FMP) in Berlin and at the University of Geneva has a crucial influence on such signaling cascades and may be an important key for the future development of therapies against these diseases. The results of the study have just been published in the prestigious scientific journal 'Molecular Cell'.

Cell growth and cell differentiation as well as the release and efficacy of hormones such as insulin depend on the presence of lipids. Lipids are small...
