Title:
PHOTOVOLTAIC POWER GENERATION SYSTEM, DC/DC CONVERTER, AND POWER CONDITIONER
Document Type and Number:
Japanese Patent JP2018153012
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a technology of adequately recovering an output reduction by PID.SOLUTION: A photovoltaic power generation system having a solar cell and converting an output of the solar cell into a predetermined AC power to be outputted includes a voltage applying portion applying DC voltage to the solar cell and performing an output recovery operation, and a stop control portion stopping an application of the DC voltage when a stop condition is satisfied after applying the DC voltage. Also, when an output corresponding information acquiring portion acquiring output corresponding information indicating a value corresponding to an output value of the solar cell is provided and the output value corresponding to the output corresponding information exceeds a threshold value, the stop control portion determines that the stop condition is satisfied and stops the application of the DC voltage.SELECTED DRAWING: Figure 5
