Title:
POWER CONVERSION SYSTEM AND POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/061424
Kind Code:
A1
Abstract:
A DC-DC converter 11 converts direct current power supplied from a solar cell 2 into direct current power having a different voltage, then, outputs the direct current power to a direct current bus 30. An inverter 21 converts, into alternating current power, the direct current power inputted from the direct current bus 30, then, outputs the alternating current power to a system 3. When the voltage of the direct current bus 30 is lower than a first reference voltage, a first control unit 12 controls the DC-DC converter 11 to perform boosting operations, and when the voltage is equal to or higher than the first reference voltage, the first control unit stops the boosting operations performed by the DC-DC converter 11. When the voltage of the direct current bus 30 is lower than a second reference voltage, a second control unit 22 controls the inverter 21 to keep constant the voltage of the direct current bus 30, and when the voltage is equal to or higher than the second reference voltage, the second control unit controls the inverter 21 so that the output power of the inverter 21 is maximum.
