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.

Claims

1. A power supplying apparatus which comprises:

transformer means for converting a high voltage into a low voltage;

non-regulated power supplying means, connected to an output end of said transformer means, for supplying a no-load voltage higher than a full-load voltage;

at least one electromechanical converting means, connected to said non-regulated power supplying means, for instantaneously supplying an output greater than a rated output upon reception of an instantaneous voltage higher than a rated voltage from said non-regulated power supplying means, said at least one electromechanical converting means requiring for its initial operation a mechanical force larger than a mechanical force required in a steady state operation;

at least one load means connected to said non-regulated power supply means; and

control circuit means, connected to said output end of said transformer means, for supplying a control signal to said at least one electromechanical converting means so as to connect said at least one electromechanical converting means to said non-regulated power supply means so that the voltage close to the no-load voltage may be instantaneously supplied thereto, said control circuit means then supplying a control signal to said at least one load means so as to further connect said at least one load means to said non-regulated power supply means so that a substantially rated voltage may be supplied to said at least one load means and to said at least one electromechanical converting means.

2. An apparatus according to claim 1, wherein said at least one electromechanical converting means comprises a solenoid so as to convert electricity into a mechanical force.

3. An apparatus according to claim 1, wherein said at least one load means comprises constant voltage power supplies which supply a DC voltage.

4. An apparatus according to claim 1, wherein said at least one load comprises high voltage power supplies which supply a high AC voltage.

5. An apparatus according to claim 1, wherein said at least one electromechanical converting means comprises a plurality of converting means to which are applied voltages close to the no-load voltage of said non-regulated power supply means at different timings, respectively.
