Abstract

In this paper presents a single-phase five-level photo- voltaic (PV) inverter topology for grid-connected system. The photo-voltaic arrays are connected to five-level inverter through the DC-DC boost converter. By implementing maximum power point tracking algorithm are producing more power from PV array. The DC power from the PV array is boosted by using the DC-DC boost converter. The boosted DC supply is applied to PWM inverter, which is controlled by PID controller. The output of inverter is AC supply, it is connected to grid. A digital proportional—integral—derivative current control algorithm is implemented in MATLAB version7.5. For dynamic performance the grid current will be almost sinusoidal. The total harmonic distortion produced by the inverter will be less. The results are compared with the digital proportional—integral current control algorithm in single-phase five-level photo- voltaic inverter.

Keywords
