PURPOSE:To provide an output modulation method in which a fluctuation component can be included easily without causing cost increase due to increase in the number of components. CONSTITUTION:In a voltage type current control system inverter where the output current is controlled based on a current command value generated depending on the difference between an input voltage from a solar cell and a voltage command value, the voltage command value is provided in the form of a digital data and two different values are set alternately at a frequency lower than the basic frequency of output voltage. |
