Advancements on Real-Time Simulation for High Switching Frequency Power Electronics Applications (Invited Paper)

Abstract

This paper presents an outlook about controller hardware-in-the-loop technology and how recent advancements in time resolution improved real-time simulation accuracy for testing high switching frequency power electronics applications. To illustrate that, the control of a dual active bridge converter (DAB) is taken as an example. The DAB converter is emulated on Typhoon HIL device, while the control algorithm is implemented on a digital signal processor from Texas Instruments. Real-time simulations are performed, highlighting the increased precision of the results obtained with the novel switch-level gate-drive signal oversampling.
