Profit analysis of energy storage bidirectional converter

What is a multi-port bidirectional converter?

In this work, a novel multi-port bidirectional converter is proposed for energy storage in electric vehicles (EV). The proposed converter has the ability to work in both bidirectional step-up (boost) and step-down (buck) modes. There are three ports in the proposed structure that the energy can flow between them.

What is a bidirectional converter?

Besides, the bidirectional converters are widely used in renewable structures and uninterruptible power supplies (UPS) with HES. These converters can transfer and balance energy between two different DC sources. Bidirectional converters are also used to transfer energy between sources and batteries in HES.

What is a bidirectional DC–DC converter?

The bidirectional DC–DC converter is one of these converters that can transfer the energy between the load and energy supplies (Shakib and Mekhilef, 2016). In HES, ESS like batteries are essential to provide the load change requirements. In ESS, the bidirectional DC–DC converters can be used to transfer the power supply energy to the DC link.

Can a multiport bidirectional converter achieve high voltage gain?

Abstract: For dc microgrid energy interconnection, this article proposes a multiport bidirectional converter, leveraging three shared half-bridges. This converter achieves high voltage gain with fewer transformer turns ratios.

What is a bidirectional multi-input non-isolated converter?

A bidirectional multi-input non-isolated converter is proposed in Akar et al. (2015) for hybrid energy storage systems in EVs. To increase the number of inputs it needs a power switch, diode, inductor and capacitor; so, the number of components, cost and volume of the converter is high.

Is a multiport bidirectional converter suitable for dc microgrid energy interconnection?

The performance of the proposed multiport converter is verified using a prototype with 400-V high voltage, 24-V low voltage, and 600-W output power. For dc microgrid energy interconnection, this article proposes a multiport bidirectional converter, leveraging three shared half-bridges.
