Title: POWER CONVERSION DEVICE AND POWER CONVERSION SYSTEM
Abstract:
In a power conversion device 10, an inverter 13 is connected, via a DC bus 40, to a DC-DC converter 21 that converts the voltage of DC power outputted from a DC power source and that outputs the converted DC power to the DC bus 40. The inverter 13 converts the DC power in the DC bus 40 to AC power, and supplies the AC power obtained through the conversion to a load 5 or a system 4. Control circuits 14, 15 control the inverter 13. When output of the inverter 13 to the system 4 should be suppressed, the control circuits 14, 15 control the inverter 13 such that output of the inverter 13 is lowered to a first target value, and notify, of a second target value which is lower than the first target value, a converter control circuit 22 that controls the DC-DC converter 21.
