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.
