What is a bidirectional DC–DC converter?

In addition, to realize energy recovery, the bidirectional DC–DC converter is required between the power battery or SC and vehicle bus to realize the flow of feedback energy. Therefore, the bidirectional DC–DC converter is the key component of HESS. It determines the performance of HESS and further affects the performance of the powertrain of NEV.

What is a bidirectional power flow converter?

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.

What is a non-isolated bidirectional DC–DC converter?

The non-isolated bidirectional DC–DC converters can be obtained by replacing the power diodes in the unidirectional DC–DC converter with active switches (such as MOSFET, IGBT). The existing bidirectional DC–DC converters mainly have the following two types: 1) Non-isolated bidirectional DC–DC converter; 2) Isolated bidirectional DC–DC converter.

Are bidirectional DC–DC conversion systems suitable for vehicle powertrain?

Topologies of bidirectional DC–DC conversion systems for vehicle powertrain have become a research hotspot with the development of NEV. On the basis of bidirectional DC–DC topology optimization, designing an excellent DC–DC conversion system while meeting the requirements for HESS is significantly challenging.
