Apparatus for generating a plurality of phase displaced periodic electrical quantities

Claim 1

IN A NETWORK FOR GENERATING PERIODIC ELECTRICAL QUANTITIES, A SOURCE OF POLYPHASE ALTERNATING POTENTIAL OF A FIRST FREQUENCY, A PLURALITY OF INDUCTORS, EACH SAID INDUCTOR HAVING END TAPS AND AT LEAST ONE INTERMEDIATE TAP, MEANS INDIVIDUALLY CONNECTING SAID END TAPS OF SAID INDUCTORS IN MESH CONFIGURATION ACROSS THE PHASES OF SAID SOURCE, A PLURALITY OF IMPEDANCE DEVICES, MEANS CONNECTING SAID DEVICES IN STAR CONNECTION ACROSS THE PHASES OF SAID SOURCE TO PROVIDE A NEUTRAL CONNECTION, A PAIR OF INPUT TERMINALS, A PAIR OF OUTPUT TERMINALS, CIRCUIT MEANS CONNECTING SAID INPUT TERMINALS AND SAID OUTPUT TERMINALS, AND INCLUDING A SWITCHING MEANS REGULATING THE FLOW OF ENERGY THROUGH SAID CIRCUIT MEANS AS A FUNCTION OF THE POLARITY OF THE POTENTIAL APPLIED THERETO, SAID SWITCHING MEANS INCLUDING A CONTROL MEANS FOR CONTROLLING THE INITIATION OF CURRENT FLOW THERETHROUGH, SAID CONTROL MEANS BEING CONNECTED BETWEEN SAID NEUTRAL CONNECTION AND EACH OF SAID TAPS FOR ACTUATING SAID SWITCHING MEANS AT A DESIRED PHASE ANGLE OF THE VOLTAGE BETWEEN SAID NEUTRAL CONNECTION AND EACH OF SAID TAPS TO PROVIDE A SEQUENCE OF PULSES AT SAID OUTPUT TERMINALS.
