With the shortage of the energy and ever increasing of the oil price, research on the renewable and green energy sources, especially the solar arrays and the fuel cells, become more and more important. How to achieve step-up and high efficiency DC/DC converters is the major consideration in the renewable power applications due to the low voltage of PV arrays and fuel cells. This book discussed an Embedded controlled Non-isolated DC to DC boost converter for solar installation system. The topology study with step-up conversion in open loop and closed loop systems proposed in these applications are covered and classified. Non-isolated DC to DC Boost converter system is simulated using Matlab and it is implemented using embedded controller. The simulation and experimental results of this system are presented and compared. This converter has advantages like fast response and delivers maximum power with minimum components.
