Comparative Analysis of High Power Density Bidirectional DC-DC Converters for Portable Energy Storage Applications

Bidirectional DC-DC converters are an essential part of modern power systems, such as electric vehicles and renewable energy. The paper presents a comparative analysis of bidirectional DC-DC converters suitable for high power density application without galvanic isolation. It is based on the comprehensive comparative analysis of conduction losses, voltage stress on semiconductors and passive component size. Continuous conduction mode of three widely used bidirectional topologies (cascaded, two-phase interleaved with and without charge-pump) are analysed. Selected analytically calculated evaluation criteria are compared for a wide range of the output voltage level. The best solution is selected for experimental realization based on GaN transistors.

Modelling and Analysis of Bidirectional DC-DC Converter

Bidirectional dc-dc converters are used lots of industrial areas such as electric vehicles, uninterruptable power supplies, fuel cells, solar panel cells as energy sources are searched in order to improve the quality of power at the transmission, distribution lines and other areas. The main contribution of this paper, applying the most common used control method on single phase isolated bidirectional full bridge dc-dc converter and comparing this control method (Extended Phase Shift – EPS) on efficiency way by with/without using snubber capacitors. In this paper, Isolated Bidirectional DC-DC Converter topology is modelled and controller algorithm is written by FORTRAN programming language. According to the results, it is observed that efficiency result of the converter, using snubber capacitors in the converter topology has higher performance than the snubberless system.

Performance Analysis of Bidirectional DC-DC Converter for Electric Vehicle Application

This paper describes bidirectional DC-DC converter fed separately excited dc motor for EV application. Battery fed electric vehicles (BFEVs) is required to function in three different modes namely: normal (steady-state) mode, acceleration mode and braking (regenerative) mode. During acceleration and normal modes the power flow is from battery to motor whereas during braking or regenerative mode the kinetic energy of the motor is converted into electrical energy and fed back to battery.
