ング電源。 A series circuit of a switching transformer and a switching element is installed in parallel with the DC power supply, and a DC conversion circuit is installed to rectify and smooth the secondary output of the switching transformer to obtain a DC output. In a switching power supply provided with a voltage control circuit that drives the switching element at a ratio, when an abnormality is detected in the DC output, there is a bypass circuit that forms a circuit in which an abnormal current flows to the DC output side, and an abnormal current is generated in the switching element. A switching power supply comprising a protection circuit that sometimes stops the switching operation of the switching element.
