The steady state stability and performance characteristics of dc grid in electric power system used for low power and building applications are very crucial. When one converter alone extends power to all loads, life of the system is reduced due to increase in temperature, and there is limitation for expansion of capacity. These limitations are overcome by parallel functioning of bidirectional extended dc-dc converter. In this paper design and simulation of three phase parallel bidirectional dc-dc converter is discussed. The ability and performance of the system to get ripple reduction and steady state output is verified through simulation and experimentation. The design proposed can be used in dc distribution system construction and low power applications.
