PROBLEM TO BE SOLVED: To improve a solarlight power generator of a type using a linkage inverter of a high-frequency link type by particularly improving an efficiency of the linkage inverter of a low output side. SOLUTION: The solarlight power generator comprises a means for monitoring a DC input voltage and input current of the high-frequency inverter 21 of a DC/DC converter 19 and operating the inverter 21 under the control (Pmax control) of tracking a maximum power point of the solar battery 17, a means for raising a modulation of the converter 19 under the control of the operation of the inverter 21 so as to raise the DC input voltage in the operating state of the Pmax control when the DC input voltage of the DC/AC inverter 20 is lower than the upper limit voltage, and a means for regulating the modulation of the converter 19 under the control of the operation of the inverter 21 so that, when the DC input voltage of the inverter 21 is raised to the upper limit voltage, the DC input voltage is held at the upper limit voltage in the operating state of the Pmax control. |
