To make a power supply circuit respond to steep growth of load.SOLUTION: A power supply circuit (10) includes: a first electric path (E1) connecting a first power supply source (20) and load (30); a second electric path (E3) connecting a second power supply source (12) and the load via a converter (15); a third electric path (E2) connecting the second electric power supply source and the load via a switch part (SW1) not via the converter; and control means (11) controlling the converter and the switch part so as to be in a first state where the power is not supplied to the load via the third electric path while power is supplied to the load from the second power supply source via the second electric path when the power cannot be supplied to the load from the first power supply source. The control means controls the converter and the switch part so as to be in a second state where the power is supplied to the load from the second power supply source via the second electric path and the third electric path when a prescribed condition on the load is satisfied in the first state.SELECTED DRAWING: Figure 6

    【課題】電力供給回路を急峻な負荷増大に対応させる。【解決手段】電力供給回路(10)は、第1の電力供給源(20)と負荷(30)とを接続する第1の電路(E1)と、第2の電力供給源(12)と負荷とを変換部(15)を介して接続する第2の電路(E3)と、第2の電力供給源と負荷とを、変換部を介さずに、切替部(SW1)を介して接続する第3の電路(E2)と、第1の電力供給源から負荷に電力を供給できないときに、第2の電路を介して第2の電力供給源から負荷に電力が供給される一方で、第3の電路を介して負荷に電力が供給されない第1の状態になるように、変換部及び切換部を制御する制御手段(11)を備える。制御手段は、第1の状態において負荷について所定の条件が成立した場合、第2の電路及び第3の電路を介して第2の電力供給源から負荷に電力が供給される第2の状態になるように変換部及び切替部を制御する。【選択図】図6
