A power source device including: a DC power source (13); an inverter (42A, 42B) to which power is supplied from the DC power source; a capacitor (CA1, CA2, CB1, CB2) connected between the DC power source and the inverter in parallel with the inverter; a reverse connection protection circuit (44A, 44B) connected between the DC power source and the capacitor and configured to block current flowing through a positive electrode-side power source line (Lpa) of the DC power source from the capacitor to the DC power source; and an overvoltage protection circuit (45A, 45B) configured to control both-end voltage across the capacitor to a voltage less than or equal to a predetermined voltage when the both-end voltage becomes greater than or equal to the predetermined voltage.
