Abstract: Renewable energy is evolved from natural sources. Photovoltaic (PV) and fuel cells are commonly used Renewable energy sources. A derived DC-DC converter is suggested for efficient renewable energy sources. An efficient Boost converter (BC) topology is discussed in this paper for renewable energy sources. The merits of this topology are reduced EME (Electromagnetic emission), fast transient response and low input current ripple. In suggested topology, 2 identical inductors and an auxiliary inductor are used to reduce the switching loss and switching stress of BC connected with PV system, used PWM technique for triggering the switches. The performance of BC along with PV system is analyzed by Matlab/Simulation software.
