Modeling and control of a half-bridge single-phase Back-to-back converter for grid-tied applications

In this paper, an alternative use of a single-phase reduced active front-end as LVDC point-to-point transmission is modeled and used as a power stage for grid-tied applications. An alternative to direct power control (DPC) is used to improve the transfer of active power between LVAC grids and microgrids. The aim is to define active power and reactive power as state variables is to simplify a control law based on a passivity-based approach. Simulations are carried out to show the effectiveness of the proposed research.
