Different models of the PV system containing many techniques of DC-DC converter are applied in this paper such as, buck converter, boost converter and buck- boost converter which are inserted to be close the power between PV array and load by varying its duty cycle, it is named maximum power point tracking (MPPT). With the use of buck-boost converters, the amount of output voltage may be set to higher or lower than the input voltage, enabling us to maintain the desired output voltage. The amount of output voltage produced is controlled by a microcontroller program which regulates pulse widths produced by PWM signals.
