description	This photovoltaic power generation drive system (1) comprises: an inverter circuit unit (4) which converts a DC voltage output from a solar panel (2) into an AC voltage according to a pulse signal, and outputs the AC voltage; a frequency limit value calculation unit (13) which calculates a limit value of an output frequency which is the frequency of the AC voltage, on the basis of the preset AC voltage frequency-voltage characteristics and the value of the DC voltage output by the solar panel (2); and an output frequency calculation unit (15) which calculates a command value of the output frequency, and outputs, to the inverter circuit unit (4), a pulse signal based on the command value or the limit value. 光伏发电驱动系统(1)具有：逆变器电路部(4)，其按照脉冲信号将由太阳能电池板(2)输出的直流电压向交流电压变换而输出交流电压；频率限制值计算部(13)，其基于预先设定的交流电压的频率-电压特性及由太阳能电池板(2)输出的直流电压的值，对交流电压的频率即输出频率的限制值进行计算；以及输出频率计算部(15)，其对输出频率的指令值进行计算，将基于指令值或限制值的脉冲信号向逆变器电路部(4)输出。
