Title:
SOLAR POWER SYSTEM AND CONVERTER
Document Type and Number:
WIPO Patent Application WO/2019/043996
Kind Code:
A1
Abstract:
Provided is a technology that can suppress a reduction of performance of a solar cell due to PID. A converter is connected between a solar cell and an inverter for converting direct current power output from the solar cell to alternating current, and the ground potential of the negative electrode of the solar cell is made higher than the ground potential of the negative electrode of the inverter when direct current power generated by the solar cell is output to the inverter side. For example, the ground potential of the negative electrode of the solar cell is set to 0 V or more without commonizing the negative electrode of the solar cell and the negative electrode of the inverter.
