Abstract

The bidirectional dual active bridge (DAB) converters play a vital role in the emerging smart-grid and Electric Vehicles (EVs) applications. The bidirectional converter plays the role of an intermediate converter between the main DC link of EV and the energy storing elements. In this work, a higher order sliding mode controller is derived based on the nonlinear Fourier switching harmonics of the DAB converter. The controller aims to regulate the converter's output voltage at the main DC link irrespective of the external disturbance as a load and variations in the voltage. The derived controller is validated by experimental results using hardware in the loop (HIL) and TI C2000 F28379D Launchpad.
