Title:
POWER CONVERSION SYSTEM, CONVERSION CIRCUIT CONTROL METHOD AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/012892
Kind Code:
A1
Abstract:
The present disclosure addresses the problem of performing accurate output suppression control in a conversion circuit (100) in regard to the occurrence of various types of output suppression factors. This conversion circuit (100) includes an inverter (13). The conversion circuit (100) carries out power conversion, at least at the inverter (13), of direct-current power output from a direct-current power supply (solar cell (2) and power storage unit (3)), and outputs the converted power as alternating-current power to a load (5) or a power system (4). A control circuit (101), upon obtaining information indicating that two or more output suppression factors have occurred, causes the conversion circuit (100) to undergo output suppression at the maximum suppression amount among two or more suppression amounts that are based on the content of the two or more output suppression factors.
