Press release: Power Electronic Device Training Courses

31 May 2023, Glasgow, UK

Power Electronic Device Training Courses Like Never Before


Power electronic devices are in the heart of all power converter applications: power supplies, motors and drives, electric cars, solar panels, wind turbines. Better power electronic devices with as little power loses as possible determine the milage of the electric cars and the efficiency of the renewable energy sources. The projected growth of the power electronics semiconductor industry exceeds the projected growth for the rest of the semiconductor industry. The current downturn of the semiconductor industry has not affected much the power electronics device manufacturers.


However, the design and the optimisation of power electronics devices are in many respects more complicated than the design of the metal oxide semiconductor (MOS) transistors in CMOS chips. According to the CEO of Semiwise Professor Asenov “If you think that you know and understand power semiconductor devices, think again. The power electronics semiconductor devices are completely new world. Have you heard about conductivity modulation, reverse recovery, on state resistance, safe operating area? All these are essential for the design and the optimisation even of the simplest power electronics device – the silicon power PiN diode.”


In the framework of the Innovate UK funded project “Virtual Manufacturing Based Power Electronics Design and Manufacturing Training Courses,” in collaboration with NMI and Synopsys, we are developing power electronics device courses for the future. For the first time the courses are entirely based on simulations and illustrations using the Synopsys TCAD tools, which are not only perfectly suited for design and optimization of power electronics devices but essential for the corresponding teaching. The lectures in our power electronics course modules are complemented with TCAD laboratories using the industry leading TCAD simulator: Sentaurus Process and Device.


The figure on the right illustrates the Si PiN diode turn-on and turn-off transients responsible for a significant part of the power losses in every power converter. The attempt to switch the diode faster increases the power losses during the turn-on and turn-off transients. The power diode related converter losses can be significantly reduced by using SiC Schottky diodes.

SemiWise develops innovative low-power CMOS transistor-level IP that improves performance and variability, and drastically reduces power consumption. SemiWise also offers simulation services, consulting and training courses to the semiconductor industry including fabless, IEDM and foundry players. The CEO of SemiWise, Professor Asenov was the founder of Gold Standard Simulations (GSS), a 2010 start-up from the University of Glasgow which developed the first TCAD based Design-Technology Co Optimisation (DTCO) tool chain. After the acquisition of GSS by Synopsys in 2016, the TCAD-to-Spice technology originally developed by GSS is now part of the Synopsys TCAD offering in the so called TCAD-to-Spice flow and continues to be developed by the Synopsys R&D division in Glasgow:  +44 07523 293 782
