Research of Setting Main Circuit Parameters of Independent Photovoltaic Power System

Inductance capacitance parameters value of main circuit devices of independent photovoltaic power system influence stability of system. In this paper, selection the suitable transistors, using a variety of algorithms to match the parameters value of capacitance, inductance. PSIM software was used to carry out modeling for photovoltaic cells, lead-acid battery, electrombile. Simulation of buck and boost DC/DC circuits, through analyzing time-domain waveform, verifys feasibility of design scheme, correctness of the algorithms. These algorithms provide a the oretical basis of main circuit setting of independent photovoltaic power system.
