Abstract: This invention is concerning a power supply device(1a, 1b) that includes a cut-off unit(S1, S2) configured to cut off voltage to be applied to a primary winding of a transformer(T1) and a coil(L1) added in series with the primary winding of the transformer(T1), a first circuit(D1) configured to cause, in a case where the voltage to be applied is cut off by the cut-off unit(S1, S2), current to flow in such a way that energy accumulated in the transformer(T1) is led to a capacitor(C1), and a second circuit(D2) configured to clamp, in a case where the voltage to be applied is cut off by the cut-off unit(S1, S2), voltage of the primary winding and the coil(L1).
