Design of BDC for Multi-Level Inverter based VSI for ESS-STATCOM Applications

This work introduces a new bidirectional converter for a voltage source inverter based on a multi-level inverter for an energy storage system static compensator application. The proposed BDC has the inherent property of balanced output voltage, low input current ripple, and high voltage conversion gain ratio with low component counts compared to the conventional BDC topologies. The different stages of the converter derivation have been explained, followed by the converter operation principle. Finally, with the aid of the simulation results, the operation of the proposed converter’s design is validated.
