<p>PROBLEM TO BE SOLVED: To provide a power conditioner for photovoltaic power generation, which performs maximum power point tracking (MPPT) control using an input current value as a control parameter and which achieves effective utilization of photovoltaic power by continuing the output of the power conditioner even when an input current sensor breaks down.SOLUTION: Input voltage control means 15 which performs input voltage control as input-output power control when an input current value is abnormal is provided separately from normal MPPT control means 13. The input voltage control means 15 controls an input voltage without using the input current value as a control parameter so that an input voltage value reaches a predetermined target voltage value.</p> |
