Abstract

In traditional system, power from battery us discharged through resistors resulting in energy wasted in the form of I²R loss. Traditional batteries are uni-directional therefore bi-directional converters are necessary in order to reverse the power flow and reuse the energy through regenerative mode. In this paper, battery integrated with proposed high voltage DC gain bi-directional isolated converter for charging and discharging purpose are discussed in a 400V DC Microgrid. Bidirectional Converters (BDC) are used in various applications like DC Microgrid for energy storage, Extra High Volt (EHV) and uninterrupted power flow. This isolated BDC has various advantages like high voltage, high gain, highly efficient, reliable, reduce loss in soft switching, simple circuit, utilizing energy efficiently, etc. The converter circuit is designed by using four Insulated Gate Bipolar Transistor (IGBT) switches, four capacitors, two inductors and one transformer. Simulation is done by using MATLAB/SIMULINK software and results are verified and discussed in this paper.
