Abstract
Techniques are described to smooth start a multilevel dual active bridge converter by pre-charging the capacitors present on the converter without requiring any additional hardware. Various phase shift angles determine the power delivered by the dual active bridge converter. By using the techniques, a predefined amount of time is reserved to pre-charge the capacitors until the capacitors reach a desired voltage after which time the smooth starting of the dual active bridge converter is initiated.
