Abstract :
This paper describes the basic characteristics of the PV module/array simulator circuit suitable for a PV system study, especially for the system using multi inverters like an AC module system. This circuit magnifies an I-V output of a small pn photo-sensor using analog technology, enabling the independent magnification adjustment of the photo-current and the output voltage of the photo-sensor. A fill factor is also easily changeable. Hence, this simulator can simulate the I-V characteristics of many kinds of PV modules or arrays. The output power of the simulator circuit can be controlled by a light intensity supplied from LED.
