ABSTRACT:
A power supplying apparatus has a control circuit which controls the timing at which at least one electromechanical converting means is connected to a non-regulated power supply, and the timing at which at least one other load is connected thereto. The control of the control circuit is such that the electromechanical converting means is first connected to the non-regulated power supply to instantaneously apply a no-load voltage to the electromechanical converting means. As a result, the electromechanical converting means instantaneously produces a great mechanical force. The subsequent control of the control circuit is such that other loads are further connected to the power supply so as to supply the rated voltage to the loads and to the electromechanical converting means.
