Nolinear power source booster suitable for photovoltaic cell

This paper proposes nonlinear power source booster which amplifies voltage and current in small size of nonlinear power source such as photovoltaic (PV) cell and wind power generator. The booster simulates large size of nonlinear power source by using a small nonlinear power source, a flyback converter, and a control circuit including variable current source. Principle of proposed booster is described at first. Prototype of the booster suitable for PV cell is built and tested to confirm the effectiveness of the booster.
