Title: Improvements in and relating to variable frequency variable voltage converting apparatus
IPC: H02K47/26
Filed: 1926-03-09
Abstract: 249,118. British Thomson-Houston Co., Ltd., (Assignees of Dewey, E. K.). March 10, 1925, [Convention date]. Frequency, changing. - A motor 11, driving a load such .as a fan 12 which load varies with speed, is supplied by variable frequency .and voltage lines 14 from a rotary transformer 13 deriving part of its energy directly from constant frequency and voltage mains 10 through switch 28, and part indirectly through direct-current machines 17, 19. At starting, a machine 20 is run up to speed from the mains 10, and then a 'switch 29 is closed so that it functions as a synchronous motor excited by a machine 21, and drives at a constant speed the machine 19. Field resistances 25, 26 are adjusted so that machine 19 functions as a dynamo and machine 17 as a motor driving the transformer 13 at synchronous speed. Switch 28 can now be closed but no power will be transmitted by lines 14. By decreasing resistance 25 and increasing resistance 26, machine 17 functions as a dynamo taking energy from machine 13 and returning it to the mains 10 through machines 19, 20. Machine 13 thus slows down with consequent increase in voltage and frequency in lines 14, thus causing the motor 11 to start up. When the machines 13, 17 become stationary the lines 14 are operating at the same frequency as the mains 10. A reversing switch 27 is thereupon thrown, allowing machine 17 to again be driven as a motor by the machine 19, but in the opposite direction, thus causing the frequency and voltage of the lines 14 to increase further with corresponding increase in speed of the motor 11. Since the above system is reversible as regards energy transference, it can be used for various purposes, for example the supply system 10 may be of variable frequency and voltage and be used to operate a constant-speed motor 10, or the machine 10 may be a variable-speed generator driven by a water-wheel and be used to supply constant frequency mains 10.
