A vehicle controller is provided for supplying a driving current to a large current load. A smoothing capacitor is previously charged to reduce the ripple component in an operating current. Thereafter, a relay contact is closed and the operating current is supplied to a load from a DC power unit. Thus, the rush current to the capacitor is reduced when supplying the operating current to the load through the relay contact. It is, therefore, possible to use a relay having a contact current capacity...
