Fast And Accurate Soft-Switching And Hard-Switching Losses Estimation For Power Converter, Application To The Dual Active Bridge (DAB) Converter

This paper presents an integrated method and workflow to estimate Dual Active Bridge (DAB) DC/DC converter semiconductor loss in losses both in soft-switching including Zero-Voltage Switching (ZVS), Zero-Current Switching (ZCS) and hard-switching. The method uses soft-switching and hard-switching energy look-up table with a frequential solver to estimates DAB loss. In case, the switching energies are not available, a virtual double pulse simulation is performed based on the datasheet characteristic. The comparison with the literature display a very fast computation time with a reasonable trade-off in accuracy.
