| Abstract |
In this paper an accurate capacitance time domain model (CTD) of the Zero Voltage Switching (ZVS)behaviour of a Dual Active Bridge considering deadtime, MOSFET Drain-Source capacitances and transformer stray inductances is presented. Building upon this a DAB model considering voltage-time errors caused by resonant commutation for Single Phase Shift (SPS) and Triple Phase Shift (TPS) is derived. Additionally a formula to calculate the optimal deadtime according to the CTD is proposed. Measurements at different operation points validate the consistency of the resonant commutation model and the voltage-time error model for the DAB. |
