| Abstract: | According to the characteristics of high-power PV array that the open circuit voltage is high and the short circuit current is large, with the dynamic capacitor charging method, the field testing technique for output characteristics of high-power PV array from the testing theory, capacitor designing, voltage and current sampling and deviation analysis and curve fitting were researched. A prototype was developed. The results of field testing prove that the prototype is precise and operates safely and reliably. |
