Abstract
Maximum power point tracking (MPPT) is used in photovoltaic (PV) systems to maximize the PV array output power, irrespective of the temperature, irradiation conditions and load electrical characteristics. A new PV MPPT control system is developed, consisting of a flyback topology based DC–DC converter controlled by a DSP. In this proposed system a multi-loop control scheme is implemented to control the flyback converter. The system is highly effective for low power applications and can be easily modified to handle various energy sources (e.g., wind-generators). The proposed multi-loop control system is implemented on low to high-end controllers and their performances are compared. Experimental results describe the performance of the proposed design prototype are in agreement with the simulation results. 8-bit microcontroller NXP89V51RD2, 16 bit DSP TMS320LF2401A, 32 bit DSP TMS320F28027 and 32-bit DSP with floating point unit TMS320F28069 are used to realized this proposed design.
