Title:
GRID-TIE INVERTER DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/157091
Kind Code:
A1
Abstract:
This grid-tie inverter connects a direct-current power supply to a commercial power system and is equipped with: an inverter main circuit unit for converting the direct-current power into alternating-current power; switches for disconnecting the inverter main circuit unit from the commercial power system; a first voltage detector for detecting inverter-main-circuit-unit-side voltages to the switches; a second voltage detector for detecting commercial-power-system-side voltages to the switches; an error compensator that holds detected error compensation values for compensating phase errors that are included in the values detected by the first voltage detector and in the values detected by the second voltage detector; and an inverter control unit for controlling the inverter main circuit unit on the basis of the values detected by the first voltage detector, the values detected by the second voltage detector, and the detected error compensation values held by the error compensator.
