Samenvatting

This paper investigates a three-level three-phase Dual Active Bridge (DAB) dc-dc converter with a star-delta connected transformer. The soft-switching region is analyzed for two and three-level operation, using symmetrical voltage waveforms, showing an increased ZVS range for three-level operation. A large number of switching modes are identified and are modeled with piecewise-linear equations. To facilitate a practical implementation of a controller, a modulation strategy is proposed that results in a Zero Voltage Switching (ZVS) operation and relies on analytical equations, using a small amount of switching modes, while obtaining close-to-minimal rms currents. The ZVS range and the proposed control strategy are supported by measurements obtained from an experimental setup.
