<p>PURPOSE:To obtain a sinusoidal output of the prescribed frequency with a simple construction by connecting the primary circuit or the secondary circuit of an induction machine with a synchronizer. CONSTITUTION:The rotor of an induction machine 1 is driven by a prime mover 2, the primary winding is connected with an AC bus 3, and the secondary winding is connected with an AC bus 3 through a frequency converter 10. Controllers 16, 17 control the frequency converter 10 in response to a deviation between the frequency and the voltage of the bus 3 and the set frequency and the set voltage. A synchronizer 4 is connected with the primary or secondary circuit of the machine 1 to control the exciting current of the synchronizer 4 to supply a reactive current to the primary or seconary circuit of the machine 1.</p> |
