An interleaved high step-up switched-capacitor converter
The 5th Annual International Power Electronics, Drive Systems and Technologies Conference (PEDSTC 2014), 2014A combination of interleaving and switched-capacitor techniques is used to introduce a high step-up converter in this paper. High voltage gain without very high duty cycle and transformer can be achieved in the proposed converter. The configuration of the proposed converter not only reduces the current stress but also decreases the input current ripple,

Non-isolated high step-up interleaved boost converter
International Journal of Power Electronics, 2014The output voltage available from renewable sources like photovoltaic panels, fuel cells and battery banks are too low to be practically utilised. Therefore, the available voltage must be stepped up considerably before connecting to the load. In this paper, a novel topology, which consists of two interleaved stages and five voltage multiplier cells, is
