simulation and hardware implementation

of incremental conductance (IncCond) maximum

power point tracking (MPPT) used in solar array power systems

with direct control method. The main difference of the proposed

system to existing MPPT systems includes elimination of the

proportional–integral control loop and investigation of the effect of

simplifying the control circuit. Contributions are made in several

aspects of the whole system, including converter design, system

simulation, controller programming, and experimental setup. The

resultant system is capable of tracking MPPs accurately and

rapidly without steady-state oscillation, and also, its dynamic performance

is satisfactory. The IncCond algorithm is used to track

MPPs because it performs precise control under rapidly changing

atmospheric conditions. MATLAB and Simulink were employed

for simulation studies, and Code Composer Studio v3.1 was used

to program a TMS320F2812 digital signal processor. The p
