Single phase supply scheme tied with Photovoltaic arrangement (PV) employed on perturbed & observed (P&O) maximum energy point tracking technique with shunt active power filter allied to a rectifier feed R-L nonlinear load. The traditional Perturbed & Observed technique maximum energy point tracking topology is applied to attained maximum output power from Photovoltaic array(PVA), Proportional Integral conventional controller with phase detector (PD) phase locked loop (PLL) synchronization are executed to produce reference current. It provide at control unit of pulse width modulation topology( PWM) is utilized in inverter to get steady output voltage. Self supported DC bus PWM converter is regulated from PV array. In proposed architecture is minimized total harmonic pollution existing in supply current owing to power electronic load (PEL). Total current harmonic pollution (THDi) is compensated using dynamic filter shunt active power filter (SAPF) and power factor obtain better later than compensation. Hence, reactive power (KVAR) is delivered through system decrease and active power (KW) enhance. The suggested scheme has been implemented by way of MATLAB/SIMULINK 2015(a) environment.

In this research paper SAPF based on phase detector circuit (PLL) for unit vector generation with traditional PI controller is implemented. This controller regulates DC side voltage, reference current generated by PI conventional controller and positive progression predictor PLL synchronization unit. Hystersis band current control (HBCC) is employed to produce gate signal for voltage source inverter (VSI). The source current THD is abridged to fewer than 5% that is in accordance IEEE-519 standards for harmonic. Active power is improved by dynamic filtering using SAPF and decrease in reactive power consequently, power factor level is become finer.
