초록

A variable frequency drive for a motor-generator/alternator set which is used to supply electrical power to computer or data processing equipment. Power failures in commercially supplied power results in aberrations and erroneous computations in computers and data processing equipment. An induction motor is used to drive a generator/alternator. The induction motor is driven below the synchronous speed of the generator/alternator and a variable speed drive increases the velocity supplied to the generator/alternator, preferably to a point above its synchro...

청구항

A method of operating a motor-generator/alternator set used to supply power to computer or data processing equipment, said motor-generator/alternator set having a synchronous speed of 1800 rpm at 60 Hz with a desired frequency variation of ±0.5 Hz which comprises the steps of a. supplying commercial power to an induction motor to drive said induction motor at a speed below said synchronous speed, b. introducing a speed changer between said induction motor and said generator/alternator so said generator/alternator can produce a frequency greater than said...
