  "textContent": "The present invention is a power supply circuit that can interrupt the supply of an operating voltage to an inductive load regardless of the supply of the operating voltage to the direct-current load, and can be manufactured at a lower cost. A first conversion section (11) converts, into a first direct-current voltage, an alternating-current voltage input from input lines (L1, L2), and applies the same between power supply lines (LH1, LL1). A diode (D1) is arranged between the power supply lines (LH1, LL1) such that an anode thereof faces toward the power supply line (LH1) side. A capacitor (C1) has both ends connected to a direct-current load (22), and is connected in series with the diode (D1). A switch section (S1) selects conduction/non-conduction between an alternating-current power supply (E1) and the first conversion section (11). A second conversion section (12) converts, into a second direct-current voltage, the alternating-current voltage input without passing through the switch section (S1), and is connected to a connection point (P1) located between the capacitor (C1) and the diode (D1) to apply the second direct-current voltage to the capacitor (C1).",
