<p>A power supply (6) for converting the power stored in a first storage portion (1) into a predetermined voltage to supply it to a load (7) comprises terminals (T3, T4) on the storage portion side coupled to the first storage portion (1), a second storage portion (3), terminals (T1, T2) on the load side coupled to the load (7), a converter portion (2) for stepping up the output voltage of the first storage portion (1) to a first voltage during the discharge of the first storage portion (1) and outputting the first voltage to the terminals (T1, T2) on the load side, a step-up circuit (4) for stepping up the output voltage of the first storage portion (1) and supplying the stepped up voltage to the second storage portion (3), and a backflow prevention circuit (5) which is disposed between the second storage portion (3) and the terminal (T1) on the load side, passes the current from the second storage portion (3) to the terminal (T1) on the load side, and prevents the current flowing from the terminal (T1) on the load side to the second storage portion (3).</p> |
