Abstract

The clean energy sources such as solar cells, fuel cells and photovoltaic are attractive in the present time as fossil energy cannot be renewed and the price is soaring in recent years. A system converting solar energy to electricity and connecting to the utility network is proposed in this paper. DC-DC converter becomes necessary in this system. In order to obtain a stable output DC voltage, an improved sliding mode controller is investigated in this paper. The reaching time can be zero by using the designed sliding surface. The additional integral term in the improved sliding surface is used to suppress the steady-state error. Simulation and experimental results are provided for verification of our design.
