Abstract
This paper presents an efficient MPPT controller. Incremental conductance algorithm is chosen for MPPT to improve the efficiency. The advantage of this algorithm is that the operating point does not oscillate around the Maximum Power Point. The algorithm also detects the atmospheric conditions. The operating point gets shifted according to the irradiance. The DC-DC converter chosen is a MOSFET based Boost converter as the Maximum Power Point is efficient in boost converter. The digital controller used is a DSP controller. The design and Simulations of MPPT are done using the MATLAB IDE link to DSP TMS320F2812. A comparison of MPPT control is done with the power control method known as limit cycle power control or sequential switching regulator. The simulation models are built using MATLAB for both the control methods and the results are compared. Index Terms— MPPT, Incremental conductance algorithm, limit cycle power control, simula...
