| Popis: | This paper explains the design and implementation of Perturb and Observe Maximum Power Point Tracking Algorithm combined with the Closed Loop Digital PI control algorithm to generate the Digital Pulse Width Modulation using Xilinx Spartan 3A DSP Field Programmable Gate Array for regulating the load voltage of DC-DC buck converter. And also concentrates on the methods for generation of DPWM techniques say Delay line based Digital Pulse Width Modulation and Hybrid based Digital Pulse Width Modulation with the 210 bit resolution. All the algorithms are developed by VHSIC Hardware Description Language coding and are implemented using Xilinx ISE 12.1 tool. The hardware results validate the satisfactory voltage regulation of PV system under continuous changing weather condition. The Hybrid based Digital Pulse Width Modulation seems to have better time transient response than the Delay line based Digital Pulse Width Modulation. |
