Abstract: This paper presents fixed frequency integral sliding mode(SM) controlled maximum power point tracking (MPPT) dc-dc boost converter to extract maximum photovoltaic (PV) energy and is connected with a single phase inverter functioning as shunt active power filter (SAPF). The SAPF has to compensate harmonic and reactive power for two stage grid connected photovoltaic (PV) system. The focusing of this paper is to design a reliable and efficient PV system employing MPPT converter and inverter with sliding mode control (SMC).The dynamic state space modeling of boost converter and inverter functioning as SAPF mode and real power supplier mode is presented. The inverter is operated by two control loops; the outer voltage loop regulates the average dc voltage on the dc link and is responsible for correctly setting the commanded magnitude of supply current and another is inner unipolar hysteresis current controller loop based on sliding mode control(SMC) law. The function of inverter is to supply maximum PV power extracted by SMC boost converter to the grid and also makes nonlinear load current harmonic compensation by keeping the grid supply current sinusoidal. The simulation models were developed from a 100 W PV with APF grid integration system using PSIM environment. The dynamic performance of converter and inverter based on SMC was presented by simulation results. The designed new PV-APF integration system is equivalent to real time hardware module.
