| Abstract |
Energy storage systems consisting of fuel cells, batteries, and super-capacitors are used to support the grid during peak loading conditions. This is achieved with the help of bidirectional DC-DC converters with boosting capability. This paper proposes a new single-stage isolated bidirectional DC-DC converter derived from the base topology of a Series Resonant Dual Active Bridge (SRDAB) called Pole Point Inductor-based SRDAB (PPI-SRDAB). It consists of a current fed boost full bridge (BFB) on the primary side and a full bridge (FB) on the secondary side. The voltage conversion ratio of PPI-SRDAB is twice when compared to SRDAB. The proposed converter is modeled using the generalized averaging method to study the dynamics of the converter. The steady-state model and small-signal model are derived, and the accuracy of the derived model is verified using MATLAB and PLECS simulations. The studies are performed on an 80 V input and 800 V output converter to demonstrate the accuracy of the proposed model. Alongside this, an experimental setup of PPI-SRDAB is populated and is verified experimentally for a high voltage gain of 10 for validating the boosting operation of the topology. |
