Solar energy is the main source of renewable energy. As the cost ofphotovoltaic (PV) panels continues to reduce, PV-based power generation becomes popular across the world and they can be either grid-connected or stand-alone systems. Currently, the global installation is over 40GW and has been growing at 50% per year since 2005 [1]. Unfortunately, the output voltage of the single PV cell is quite low (about 0.7 V) and thus the output voltage of the PV module is limited to usually 35 V. In order to connect to the power grid, the PV bus voltage should be higher than 350 V for a 220V/50Hz AC grid. Therefore, a high-voltage gain is needed to convert the low PV cell voltage into high voltage for grid connection.
