POWER CONVERSION APPARATUS, CONTROL SYSTEM, AND CONTROL METHOD

摘要

PCS 400 operates in any one of a standard mode and a charging mode within a plurality of operation modes at a time when PV 100 operates. The plurality of operation modes include the standard mode in which an output of the PV 100 is converted into AC power and the AC power is supplied to grid 1 and/or load 300 and the charging mode in which the output of the PV 100 is supplied to storage battery 200. An output voltage of the DC/DC converter 410 is different in the standard mode and in the charging mode.

主权项

1. A power conversion apparatus that operates while switching a plurality of operation modes, the plurality of operation modes including a first mode in which an output of a power generation apparatus is converted into AC power and the AC power is supplied to at least one of a grid and a load and a second mode in which the output of the power generation apparatus is supplied to a storage battery, the power conversion apparatus comprising:
a DC/DC converter that is connected to a power source line of the power generation apparatus; and a DC/AC converter that is connected to the DC/DC converter through a first power line, wherein the DC/DC converter is connected to the storage battery through a second power line which branches from the first power line, and an output voltage of the DC/DC converter is different in the first mode and in the second mode.
