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.
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.
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.
Since the output voltage has a switched waveform, a filter using capacitor, inductor or both can be added to the output to smooth out the ripple. This example explains how the bidirectional power conversion is carried out. Here we use an inductor to smooth out the output ripples, so that it can be connected to a battery V b.
Moreover, only two power switches are utilized in the proposed converter, which makes it easy to transfer the power between the sources. The suggested converter can be worked in energy storage system (ESS) due to the ability of step-up and step-down operation principles. Thus, it can charge and discharge the ESS with high voltage conversion ratio.
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.
