Power MOSFET is the basic control element in all types of power electronic converters. Recent studies are focused on charging battery using solar energy to eliminate the energy crisis. This paper analyzes the losses associated with power MOSFET used to charge batteries from solar energy. N channel and P channel HEXFET power MOSFET devices are chosen. Efficiency of the Photo-Voltaic (PV) charger is derived for different switching frequencies of device. Efficiency of PV system with N channel device is better with complicated gate driver circuit, compared to P channel device.
