A coupling system for an induction motor type generator (10) to an A.C. power line (18) wherein an electronic switch means (28) which is controlled by a control system (30) is regulated to turn “on”at a relatively late point in each half cycle of its operation whereby the energizing power supplied b

A coupling system for an induction motor type generator (10) to an A.C. power line (18) wherein an electronic switch means (28) which is controlled by a control system (30) is regulated to turn “on”at a relatively late point in each half cycle of its operation whereby the energizing power supplied by the line (18) to the induction motor type generator (10) is decreased and the net power delivered to the line is increased.

An electrical generating system comprising: an induction motor/generator that is mechanically driven through a shaft; means for rotating the shaft of said induction motor/generator; an alternating current power supply line; electronic switching means electrically connecting said power line to said induction motor/generator so as to transmit power therebetween; said switching means adapted to switch on for conduction between said power line and said induction motor/generator in response to a trigger signal and switch off when the current ceases to flow; control means for providing a trigger signal to said switching means at a relative late point in each half-cycle of a-c power of said power line whereby the energizing power supplied to said motor/generator will be decreased and thereby the net power delivered to the line from said induction motor/generator will be increased. A coupling system for an induction motor/generator to an a-c power line, such induction motor/generator being subject to varying mechanical rotational shaft speeds, comprising: electronic switching means electrically connecting said a-c power line to said induction motor/generator so as to transmit power therebetween, said electronic switching means adapted to switch on for conduction between said power line and said induction motor/generator in response to a trigger signal and to switch off when the current goes to zero; control means for providing a trigger signal to said electronic switching means at a relative late point in each half-cycle of a-c power of said power line whereby the energizing power supplied to said motor/generator will be decreased and thereby the net power delivered to the power line from said induction motor/generator will be increased.
