Semiconductors and power electronics

The electrification of society is placing new demands on power electronics. Traditional silicon-based semiconductors are reaching their physical limits in terms of voltage and temperature, leading to significant energy losses with each conversion of electrical energy. Next-generation products – from electric cars to 5G networks – require advanced materials such as silicon carbide and gallium nitride, but few companies have the resources to build their own manufacturing capacity or the specialist expertise needed to develop these materials.

RISE gives you access to the entire development chain for energy-efficient semiconductors without you having to invest in your own infrastructure. In our two cleanroom laboratories, Electrum and ProNano, we design, model and manufacture components in silicon carbide (SiC) and gallium nitride (GaN) that reduce energy losses by up to two-thirds compared to silicon. This provides tangible benefits such as a 10-20 per cent longer range in electric cars and dramatically improved system efficiency. We help small and medium-sized companies in particular to scale up their innovations by offering both expertise and advanced equipment, enabling you to get to market faster without your own capital costs for clean rooms and process equipment.

A revolution in blue light at the micro level

In the summer of 2023, a highly controlled blue light from Polar Light Technologies' microLEDs in the shape of small pyramids appeared for the first time. The breakthrough could mean a revolution in the global display market, which is about to undergo a transformation – both in terms of technology and sustainability.

Silicon carbide powering the energy revolution

Silicon carbide is a material used to create new types of energy-efficient semiconductors that can save up to 20 percent of the battery time for electric cars. The Swedish startup Ascatron manufactures wafers and components in silicon carbide. In 2020, the semiconductor developer was acquired by the American electronics giant II-VI. But their journey began as a part of RISE.

Curiosity is all - Mietek Bakowski

For over four decades, Dr Mietek Bakowski has worked with research and development in semiconductor materials for high-voltage environments, making him an international authority in Power Electronics - a field that has slowly made its way into powertrains for electric cars, boats, and aircraft. The field is based on the need for tougher materials to withstand the high voltages required as our world becomes increasingly electrified.

Collaboration on Power Semiconductors and Advanced Materials

RISE Research Institutes of Sweden and Kwangwoon University has signed a Memorandum of Understanding (MoU) to enhance cooperation in power-semiconductor development and advanced materials research. The agreement was formalized at a signing ceremony in Jeju, South Korea.

The partnership builds on a solid foundation of existing joint activities. With the MoU, both partners commit to strengthening practical academia–industry cooperation through joint research, talent exchange, international symposia, and internship programs.

Dependable electronic systems - IEC 61508

IEC 61508 - Safety-related systems

This two-day course in standard IEC 61508 covers the requirements for both systems - hardware and software - in detail. The aim is that participants shall acquire sufficient understanding of IEC 61508 and how it is structured. This will enable self-sufficient work.

Purpose

To gain an understanding of the most essential parts of IEC 61508 and to provide a sufficiently detailed knowledge. This will enable you to proceed and apply the standard yourself.

Target group

Hardware Designers, Programmers, Test Engineers, System Engineers, Project Managers, Product Managers, Quality Managers, Operations and Maintenance Personnel. 

Content

Initially, the course covers general concepts and establishes how the standard can be applied. The course includes, among other things, the following parts: 

  • Going through the connection between IEC 61508 and various industry standards
  • A description of which phases included in the so-called Safety Life Cycle
  • A description of the requirements on Safety Management determined by the standard
  • A review of the requirements of the standard applied to independent 3rd party review of the safety circuit
  • Risk analysis and identification of safety functions
  • Definition of safety requirement specification
  • Hardware design
  • Reliability calculations of hardware (e.g., determination of PFHd, PFD and SFF)
  • Software engineering
  • Verification and validation
  • Operation & maintenance of safety functions

The course theory is alternated with practical examples.

Testing of UCATT Laser Engagement Interface (U-LEIS) in accordance with SISO-STD-016-00-2016

Name of service (page headline, shown in promos – maximum of 70 characters incl. spaces): UCATT – Urban Combat Advanced Training Technology Standards Lead (include SEO-words and the main benefits for your target groups. Stick to one paragraph, maximum 2-3 sentences):

Gain complete confidence that your weapon-firing simulators and target simulators meet the highest standards. We offer accredited testing according to SISO-STD-016-00-2016, ensuring that your systems operate smoothly and reliably with those from other manufacturers.

Purpose/Benefit:

During military exercises, laser-based weapon-firing simulators and target simulators are often used. By standardising how weapon-firing simulators and target simulators encode and decode the optical laser engagement signal, it becomes possible for units from different manufacturers to operate together on the combat training field. This is particularly important when different armed forces, such as those within NATO, conduct joint live simulation combat exercises.

As an independent testing institute with extensive metrological expertise, we perform accredited testing of both weapon-firing simulators and target simulators. Independent verification that a product meets the requirements of the standard is often a prerequisite set by procurers and buyers.

Method (what/which methods are used to perform the service):

The testing is carried out with equipment and an accredited method developed by RISE, based on the standard SISO-STD-016-00-2016 and the corresponding test plan SISO-REF-073-00-2020. The testing is performed in RISE’s laboratory, or upon request, at the customer’s site.

Delivery (what does the client get after performed service – e.g. a report, certificate etc.):

The results of the testing are summarised in a report, where each subtest in the test plan (SISO-REF-073-00-2020) is presented separately.

Characterisation of thermal converters with a Josephson standard

KaraTe

By developing new methods for characterising thermal converters, an independent realisation of the SI units for alternating voltage (V), alternating current (A) and electrical power (W) will be established at RISE. This will lead to a more secure traceability chain and better measurement uncertainty for calibration in the low frequency range.

To realise the units for alternating voltage, alternating current and electrical power with the lowest measurement uncertainty at RISE, thermal converters are used. With a thermal converter, an unknown alternating voltage (ac) can be compared to a known direct voltage (dc) that is traceable to natural constants via the Josephson effect. Each thermal converter has an error (ac-dc difference) that must be characterized as part of the realisation. In this project, new characterization methods will be developed with a programmable Josephson standard, which can generate precisely defined (quantised) direct voltages and alternating voltage signals with calculable RMS value.

After the project, RISE will be one of few NMIs (National Metrology Institutes) in the world with its own realisation of the alternating electical units, which makes us independent of external actors and increases the security of the traceability chain. The new methods will also be used at RISE to improve measurement uncertainty during calibration in the low-frequency range (<1 kHz), especially at 3–10 Hz, since measuring instruments with significantly better performance in that range than before have come onto the market.
