The abstract of this paper to design and implementation of bi-directional dc-dc converter for energy storage system. In upcoming generation, the global energy level may increase 2% per year. The conventional electrical power generation produce environmental pollution and global warming. By using the renewable energy like solar and geo thermal energy we can consume the power generation without any natural causes. It also gives clean and eco-friendly. The energy storage device and unidirectional boost converter (UDC), are also maintain constantly and made the energy conversion. This type of method converts into AC to DC, Boost the level of voltage and get output of consistent from the solar panel. The solar panel, inverter, bi-directional converter (BDC) are connected to load/grid. This is called solar energy electrical system (SEES). The system is operatives in five different modes that is solar sourced battery output mode, solar sourced battery mode, battery sourced output mode and grid battery mode. This circuit were designed through MATLAB/SIMULINK with all the modes. This type of system includes by three phase uncontrolled rectifier conversion for AC to DC, buck-boost operation for BDC and rectifier/inverter unit. These are the closed loop operation.
