The distributed generation (DG) systems based on the renewable energy sources have rapidly developed in recent years. These DG systems are powered by micro sources such as fuel cells, photovoltaic (PV) systems, and batteries. The micro grid concept consists of two stages, in the first stage the low level voltage from the pv cell is converted to high level voltage by using DC-DC converter. In th...
This paper proposes a novel high-efficiency isolated three-port bidirectional DC/DC device for photovoltaic (PV) systems. The device contains a high step-up converter for PV modules to supply power to the DC bus, and a bidirectional charge/discharge control circuit for the battery with an improved boost-flyback converter. When the PV modules supply sufficient energy, their output can be stepped...
For battery-powered electronic products, one way to extend battery life is to use a versatile step-up/step-down DC-DC converter. A new versatile step-up/step-down switched-capacitor-based converter structure is proposed, and its efficiency is analyzed. In the step-down case, the efficiency is the same as, or even better than the efficiency of linear regulators. key words: DC-DC converter, switc...
In this paper, a new non-isolated transformerless high step up Dc-Dc converter with low voltage stress on the active switch for solar energy application is proposed. The converter topology is simple, which makes the control scheme simple. In this converter, only one active switch is used which makes reducing the switching power loss. The voltage gain of the proposed converter is higher than the...
