Procedure for the generation of artificial energy for the generation of solar photovoltaic energy and power supply apparatus that simulates the generation of solar photovoltaic energy

摘要

A method for artificially generating the output characteristic of a solar photovoltaic power generation module, and a solar photovoltaic power generation simulator power-supply apparatus having that output characteristic with the internal power loss reduced. The solar photovoltaic power generation simulator power-supply apparatus includes an IV storing means for storing, as IV curves, the voltage/current characteristics of solar photovoltaic power generations; an IV reading means; and means for generating an IV characteristic as an output target value of automatic control. The solar photovoltaic power generation simulator power-supply apparatus reads a designated particular IV curve from among the stored IV curves to generate a control signal for holding V associated with I on this curve, and supplies this control signal to a semiconductor switching element, which controls the power, thereby artificially generating a solar photovoltaic power generation output characteristic. The solar photovoltaic power generation simulator power-supply apparatus includes a control signal circuit that controls the power so as to maintain the output at the voltage associated with the current on the designated IV curve; and a power conversion main circuit from which series resistors have been eliminated.
