Abstract

1,018,053. Control of A.C. motors. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. Jan. 10, 1963 [Jan. 10, 1962], No. 1235/63. Heading H2J. A squirrel cage motor having a star-connected stator winding is connected to a D.C. source Uo through an inverter comprising semi-conductor devices 1-6 for controlling the stator frequency. Power is returned from the stator winding to the source through diodes 19-24, choke 25, and diode 26. The return current is pulsed by triode 27 which is controlled to maintain the motor nux at an optimum value. The return circuit may include a transformer.
