Hardware design engineers use real-time testing platforms (RTP) to design and implement the power electronic converters (PEC). The newly introduced DSPs have multicores and higher clock speeds, making them capable of real-time applications. In this context, the use of DSPs as cost-effective real-time testing platforms is explored. The proposed testing platform is validated for a buck converter, a series resonant dual active bridge converter (SRDAB), and a grid-connected inverter (GCI) system. This work aims to present a simple and fast low-cost testing platform, thus reducing the lead time for system development. The real-time simulation data from RTP and MATLAB simulation data are verified with experimental data. It is shown that the DSP-based real-time testing approach provides validated, low-cost solutions for real-time testing platforms.

Energy storage systems consisting of fuel cells, batteries, and super-capacitors support the grid during peak loading conditions with the help of bidirectional DC-DC converters with boosting capability. 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) is proposed. The proposed converter is modeled using the generalized averaging method. The steady-state model and small-signal model are derived, and the accuracy of the derived model is verified using MATLAB and PLECS simulations. Alongside this, an experimental setup of PPI-SRDAB is populated and verified experimentally to validate the operation of the topology.
