Abstract:
DC transformer (DCX) is a DC-DC converter that operates at a fixed voltage conversion ratio, allowing for optimized design under constant voltage conditions and the potential for higher performance. The Series-Bridge DCX (SB-DCX) topology has recently been used in DCX applications due to its inherent, uncontrolled DCX operation. However, a convenient and scalable time-invariant dynamic model for this topology is missing. This digest examines the challenges of developing a time-invariant dynamic model and proposes the use of half-cycle averaging that results in a linear time-invariant (LTI) DC-terminal dynamic model with a convenient circuit-based description. Simulation and hardware results are presented, demonstrating a strong correlation between the observed dynamic behavior and the predictions of the developed model.
