Photovoltaic systems for renewable energy are being deployed with the common purpose of delivering optimal performance over a range of operating conditions. Direct Current to Direct Current (DC-to-DC) boost power converters are important in these solar power systems because they increase the input voltage of a solar array under certain conditions. The energy transfer from the Photovoltaic (PV) module to the battery is highly efficient when using a boost converter in in combination with methods such as Maximum Power Point Tracking (MPPT) or Pulse Width Modulation (PWM). The voltage conversion is achieved by storing energy in an inductor and releasing it at a higher voltage to the load. Boost converter parameters include component selection for maximum achievable voltage and current outputs for varying input from PV panel. This paper provides the design details of the boost voltage conversion from 40 to 48 VDC with maximum current output up to 9 A for battery charging requirement. The paper also discusses feasible enhancement techniques to improve the stability of system. Experimental work has been carried out using a high speed MOSFET as a switch providing 48 V, 432 W output power at 100 KHz switching frequency and the circuit operating in continuous conduction mode.
