Inverter battery side BDC

What is a BDC converter?

y exchange between storage device and the rest of system. Such a converter must have bidirectional power flo capability with flexible control in all operating modes.In HEV applications, BDCs are required to link di ferent dc voltage buses and transfer energy between them. For example, a BDC is used to exchange energy between main b

What are the applications of bidirectional energy transfer (BDC)?

ty of bidirectional energy transfer between two dc buses. Apart from traditional application in dc motor drives, new applications of BDC include energy storage in renewable energy systems, fuel cell energy systems, hybrid electri

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.

Can a battery and BDC be directly connected for charging and discharging?

For the battery and BDC to be directly connected for charging and discharging, the BDC must meet the following characteristics: A bidirectional converter capable of charging and discharging the battery is required. A low-profile converter, matching the height of the battery to improve space utilization and complexity of the connection, is required.

How does a BDC control a battery?

Within the designed system, the BDC controls the bidirectional power flow between battery and DC-link. During the charging stage of a battery working in buck mode, the battery is fed from the DC-link, and the battery current is regulated by the BDC through the use of PI controller.

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.
