Abstract:
1. A maximum power follow-up control apparatus for setting an operating voltage of a power converter that converts an output voltage of a power generator into AC power so as to make a power point of an output power of the power generator, which corresponds to an output level of the power generator, follow-up with a maximum power point, the maximum power follow-up control apparatus comprising: an approximate function storing part that stores an approximate function related to a maximum power point corresponding to the output level of the power generator according to characteristics of the output power and the operating voltage; and a control part that calculates an operating voltage value corresponding to the present output power on the basis of the approximate function as stored in the approximate function storing part and that sets the calculated operating voltage value as an operating voltage value of the power converter in order to make the power point related to the output power in correspondence with the output level of the power generator follow up with the maximum power point.
