For the growing energy distribution challenges, active distribution networks are found to be an ideal choice. With the rapid development of semiconductor and power electronic techniques, the dc distribution system is ready as an alternative scheme to the existing ac distribution systems due to its high power quality and reliability performance. Half Bridge Converter (HBC) or Full Bridge Converter were the commonly used topologies. Among them, Half bridge converter has significant role in power electronics and drives application. The converter can be proposed in different ways according to the area of application. A modification is made with the existing HBC by the addition of LCL filter at input side to reduce the inrush current, voltage stress on switches and di/dt losses. The main advantage of employing the proposed converter is to reduce the input current ripple without adding a large input filter. Hence the above mentioned HBC with LCL filter is the proposed topology which can shape the input current waveform to a non pulsating fashion.
