Small Signal Average Switch Modeling and Dual Loop Control of Bidirectional Integrated Converter for G2V and V2G Applications in Battery EVs

Onderzoeksoutput: Conference paper

Samenvatting

This paper proposes a bidirectional integrated converter configuration, which utilizes the traction inverter, motor windings and DC/DC converter during charging operation. This topology can operate in two modes: Grid-to-Vehicle (G2V) and Vehicle-to-Grid (V2G). Hence, during the G2V the traction inverter utilizes as AC/DC converter, while during the V2G, it operates as DC/AC inverter and the 3-phase interleaved DC/DC converter operates in both buck and boost mode, respectively. For a precise control system design and to achieve good performance and stability, a small-signal modeling is widely used for the power electronic converters (PECs). In this paper, small-signal based transfer functions are utilized to design a Type-II K-factor based controller. Finally, MATLAB/Simulink® is used to validate the proposed topology’s charging and discharging capability and performance.
