A power supply circuit comprises a bridge circuit that has four rectifier elements connected and produces a rectified voltage between a positive side output terminal and a negative side output terminal of the power supply circuit, two of the four rectifier elements being connected to the negative side output terminal, a current detection element with which to detect a current, a first switching element that is connected in series to the current detection element and together with the current detection element is connected in parallel with one of the two rectifier elements, and a second switching element that is connected in series to the current detection element and together with the current detection element is connected in parallel with the other of the two rectifier elements. Based on a result of detecting with the current detection element, switching timings of the first and second switching elements are controlled.
