Such a converter must have bidirectional power flow capability with flexible control in all operating modes. In HEV applications, BDCs are required to link different dc voltage buses and transfer energy between them. For example, a BDC is used to exchange energy between main batteries (200-300V) and the drive motor with 500V dc link.
AC/DC topologies Bi-directional converters use the same power stage to transfer power in either directions in a power system. Helps reduce peak demand tariff. Reduces load transients. V2G needs “Bi-Directional” Power Flow. Ability to change direction of power transfer quickly. High efficiency >97% (End to End) at power levels up to 22KW.
As energy transfer in either direction is required for the system, each dc-ac converter must also have bidirectional energy transfer capability. With the same token, the dc buses in this structure must also be able to either generate or absorb energy.
Power transfer from power generation from RES into storage systems is required to result in a highly efficient conversion. The appropriate bidirectional DC–DC converter should be involved to realize it. In addition, it improves the performance of the buck–boost converter by continuously applying additional circuits or components.
For DHB configuration it will lead to Similar to DAB configuration, the maximum power transfer is at |φ|=90 degrees. So the converter full range of bidirectional power transfer can be gained by controlling phase shift in -90 to +90 range.
