Abstract: This paper presents simulation implementation of incremental conductance maximum power point tracking (MPPT) used in solar array power system. The comparative study between two most popular algorithms techniques Which is incremental conductance Algorithm and perturbs and observe algorithm two different converter cuk and buck converter used for comparative in this study few comparison such as voltage, current and power out for each different combination has been recorded? The resultant system is capable of tracking MPPS accurately and rapidly without steady state oscillation and also its dynamic performance is satisfactory. The main different of the proposed system to existing MPPT system is eliminating the PI (proportional integral) control loop and investigating the effect simplifying the control circuit.MAT LAB/Simulink were employed for simulation studies and CCStudiov3.1 was used to program a TMS320F2812DSP.The propose system was developed and tested successfully in laboratory on the PV solar panel. Experimental result indicates the feasibility and improved functionality of the system
