Abstract:
This paper presents a single phase five level inverter topology for grid connected PV system. A new pulse
width modulated (PWM) control scheme was introduced. In this scheme two reference signals identical to each other
and a triangular carrier wave was used to generate the switching signals. MPPT algorithm was implemented to catch
the maximum power point in the PV array. A proportional-integral control algorithm was also implemented for
obtaining high dynamic performance.
