Technical FAQs 4

Does a bidirectional DC-DC converter need a battery backup system?

Because it is bidirectional, it does not require another DC-DC converter or AC-DC converter to charge the battery. A battery backup system application is used in this paper for the control of this converter. Figure 2 shows the topology of this new isolated bidirectional DC-DC converter.

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

The bidirectional DC-DC converter (BDC) is used as an interface circuit between power generation unit and battery to control the charging and discharging mode of operation of battery . BDC topology has distinguishing features such as bidirectional power flow, transformer-less operation and The Authors, published by EDP Sciences.

What is a switched inductor based bidirectional DC-DC converter (BDC)?

A switched inductor based bidirectional DC-DC converter (BDC) for high voltage gain is designed for electric vehicle (EV) and solar PV installation applications.

How does BDC control the power flow between battery and DC link?

In the designed system, BDC controls the bidirectional power flow between the battery and DC link. Specifically, in the charging stage of battery operating in buck mode, DC-link supplies the power to the battery and BDC regulates the battery current using proportional-integral (PI) controller.
