PROBLEM TO BE SOLVED: To provide a booster connection box that enables a power conditioner to satisfy an operating continuation requirement in a period of specific accident when voltage momentarily decreases, and to provide a power generation system using the booster connection box.SOLUTION: In a booster connection box 1 that inputs output voltage of a solar cell module to a power condition 2 by boosting it to a target voltage by means of a booster circuit 7, a control section 8, which exerts proportional control and integral control and generates from a target voltage and an output voltage of the booster circuit 7 a boosting control signal to be applied to the booster circuit 7, exerts specific control when output stop of the power condition 2 is detected. In specific control, a boosting control signal is generated using a value obtained by averaging integral values in integral control in a fixed period before the specific control, and this boosting control signal is applied to the booster circuit 7 for a predetermined period. Thus, when a power system 3 resumes from a momentary voltage decrease, a power condition 2 is able to maintain 80% or more of power output before the momentary voltage decrease.SELECTED DRAWING: Figure 1 |
