Consortium Halves Energy Loss For Power Devices
The NeuLand project team says the key to reducing energy losses is by using SiC and GaN-on-silicon
New semiconductor materials could mean 50 percent less energy loss in switched-mode power supplies for PCs, flat-screen televisions, servers and telecommunications systems and could make solar inverters even more compact and cost-efficient.
The partner companies of the research project “NeuLand" have developed highly-integrated components and electronic circuits which made it possible to reduce energy loss in circuits by 35 percent as early as during tests in ongoing research activities.
The NeuLand project was funded by the German Federal Ministry of Education and Research (BMBF) with a total of approximately €4.7 million. This project was directed by Infineon Technologies.
Key to cutting energy losses in half
The key to reducing energy losses by half is use of the semiconductor materials SiC and GaN-on-silicon, whose electronic properties enable compact and efficient power electronics circuits. Today Infineon already uses the material SiC in its JFETs and diodes for the 600V to 1700V voltage class.
These power semiconductors are primarily used in switched-mode power supplies for PCs or televisions and in motor drives. In the future they may also gain major significance for solar inverters. And after thatt heir use solar inverters could considerably profit.
Before NeuLand, SiC was a very expensive wafer material. But NeuLand says its research has shown there are now more SiC vendors and the number of possible applications has grown. The project partners were able to demonstrate that the efficiency of power electronics can be increased by more than a third using SiC and GaN-based components.
Solar inverters for example profit from considerable material savings with no change in effectiveness, making them even more cost-efficient. However, results also showed that the cost of SiC components will have to drop even more for the wide-scale application in solar inverters and that for GaN-based components further intensive research is required on reliability, service lifetime and costs.
Aixtron was represented as an equipment provider for semiconductor production, while as a wafer manufacturer SiCrystal was on board for SiC. Semiconductor manufacturer Infineon researched the power semiconductor devices and the production steps for SiC and GaN-based components, while the system technology expertise in the solar sector was provided by SMA Solar Technology.
With NeuLand the project partners were able to further expand their respective proficiencies in future-oriented SiC and GaN technologies along a very wide segment of the value creation chain.
NeuLand is an abbreviation from the German for “Innovative power devices with high-energy efficiency and cost effectiveness based on wide bandgap compound semiconductors".
The three-year research project was funded by the BMBF as a part of the call for proposals on "Power Electronics for Energy Efficiency Enhancement" (LES) in the German Federal Government’s program "IKT 2020 - Research for Innovation". The objective of IKT 2020 is to strengthen Germany’s leading position in electronic technologies.

AngelTech Live III: Join us on 12 April 2021!
AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!
Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.
2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.
We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.
We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.
Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.
Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.
So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
