PURPOSE:To improve the reliability of a power supply with a compact and inexpensive structure by calculating an optimum route against the power abnormality based on the working state and the capacity of each load and switching the loads via a load switching device. CONSTITUTION:When either one of power supplies 3-1-3-3 has the abnormality, a power supply route calculating part 1-1 of a power supply controller 1 receives the information on said abnormality. Then the part 1-1 calculates a power supply route to supply the power to the prescribed one of the loads 5-1-5-3 from the normal one of supplies 3-1-3-3 based on the working states of the loads 5-1-5-3 and the capacities of these loads. Then a load switching device 2 supplies the power to the loads from the power supplies via the calculated supply route. Thus it is possible to improve the reliability of a power transfer control system against the power abnormality with use of a power supply having a small capacity compared with a fully duplex case. |
