초록
In this paper, compare and analyze existent MPPT algorithms. Existent algorithms have defects which don't generate it in a partial shade or low insolation. Therefore, to supplement it, we design improved IncCond algorithm consisted of a Aux. switch and capacitor with Generation Control circuit which can always obtain maximum generation power at the factor which is reduced generational efficiency by partial shade. Generation Control circuit is method which can always get maximum output power as it regularly controls each voltage of serial connected solar cell. Accordingly, it can improve efficiency and confidence of utility interaction inverter. Construction of system use a low price PIC16F87X. We analyze special character according to system operation through simulation and prove the validity through experiments.
