<p>This power supply circuit (100) includes a comparison means (D1) configured to compare the value of a voltage based on a voltage input to a primary winding (1a) of a transformer (1) with the value of a voltage based on the full-wave rectified voltage of an alternating current source, a load circuit (8) supplied with power output from the secondary side of the transformer, and a stop means (5, 6, 9) configured to stop power supply to the load circuit.</p> |
