Title: Improvements in or relating to voltages and frequency regulating circuits for power supply sources
IPC: H02P9/28
Filed: 1944-09-27
Abstract: 618,047. Automatic control systems. SUBMARINE SIGNAL CO. Sept. 27, 1944, No. 18466. Convention date, Aug. 6, 1941. [Class 38 (iv)] Voltage; frequency.-A motor generator is automatically controlled to maintain the frequency and the voltage of its A.C. output constant by independent circuits controlling rectifiying tubes associated respectively with the field windings of the motor and the generator. Fig. 1 shows a D.C. motor having a field coil 5 in series with a resistance 6 driving an alternator 3 having a field coil 8 in series with a resistance 9. Connected across the generator 3 is a transformer 13, the secondary 15 of which is shunted with a condenser 16 to form a resonant circuit, the output of which is passed through a rectifier 17 and resistor 18 which has an adjustable tap 19 connected through a bias battery 20 to the grid 21 of a thermionic valve 22. This grid controls the flow of current through the valve 22 which controls through resistor 26 the potential of the grid 28 of the thyratron tube 29, the anode of which is connected to the field rheostat 6 while the cathode is connected to the negative side of line 7, a condenser 36 being connected across the tube. Variations in frequency cause a change in voltage in the resonant circuit 15, 16 which varies the bias on the thyratron tube 29. When the tube fires, the grid 28 loses control and this is returned by the condenser 36 which by its discharge makes the potential from anode to cathode zero extinguishing the arc and permitting the grid to gain control. A rise in frequency causes the tube to discharge, permitting more current to flow through the field 5, a decrease in frequency acting in the opposite way. In the circuit, the balance is so adjusted that the tube 29 will operate a portion of the time when the frequency is normal and when it drops below it will operate less and when above it operates more. The voltage control 11 operates in a similar way in the alternator field winding 8, but there is no tuning in the circuit, the negative drop obtained by the connection 45 is obtained through rectifier 42 from the secondary of the heating transformer 40. An extra valve is included and the circuit is so arranged that for normal voltage conditions the thyratron tube 54 will operate a portion of the time and if the voltage decreases the tube will operate more frequently.
