POWER SUPPLY SYSTEM AND HEAT PUMP SYSTEM |
摘要 |
The object of the present invention is to prevent an increase in cost even when solar power generation is utilized. A power supply system includes: a VVVF inverter 11 which converts DC power to AC power and outputs an AC voltage falling within a predetermined voltage value range; a solar power generation panel 14 which converts solar energy to DC power and which is capable of outputting a DC voltage equal to or greater than an upper limit voltage value of the voltage value range to the VVVF inverter 11; a AC-DC converter 15 which converts the AC power supplied from a power system S to DC power and outputs a DC voltage of a specific value that is equal to or greater than a lower limit voltage value of the voltage value range to the VVVF inverter 11 in order to compensate for a shortage of power supplied from the solar power generation panel 14 to the VVVF inverter 11; a first diode 12 which allows a current to flow in the direction from the solar power generation panel 14 to the VVVF inverter 11; and a second diode 13 which allows a current to flow in the direction from the AC-DC converter 15 to the VVVF inverter 11. |

1. A power supply system comprising:
a DC-AC converter which converts DC power to AC power and outputs an AC voltage falling within a predetermined voltage value range; a solar power generation unit which converts solar energy to DC power and which is capable of outputting a DC voltage that is equal to or greater than an upper limit voltage value of the voltage value range to the DC-AC converter; an AC-DC converter which converts AC power supplied from a power system to DC power and outputs a DC voltage of a specific value, which is equal to or greater than a lower limit voltage value of the voltage value range, to the DC-AC converter in order to compensate for a shortage of power supplied from the solar power generation unit to the DC-AC converter; a first backflow prevention unit which allows a current to flow in the direction from the solar power generation unit to the DC-AC converter; and a second backflow prevention unit which allows a current to flow in the direction from the AC-DC converter to the DC-AC converter. |
