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.

Do DC-AC converters have bidirectional energy transfer capability?

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.

How can a bidirectional DC–DC converter be optimized?

The optimization calculation method can be used to improve and optimize bidirectional DC–DC converters based on existing interleaved, quasi-Z source, cascaded, and other topologies. This can be done in terms of decreasing the volume of energy storage elements, reducing the stress of devices, and reducing switching loss.

What is a bidirectional DC-DC converter (BDC)?

Bidirectional dc-dc converters (BDC) have recently received a lot of attention due to the increasing need to systems with the capability of bidirectional energy transfer between two dc buses.

What is the research status of bidirectional DC–DC converter?
