A CONVERTER SYSTEM FOR CONVERTING UNREGULATED A.-C. INPUT POWER TO FREQUENCY-REGULATED AND AMPLITUDEREGULATED POLYPHASE OUTPUT POWER COMPRISING, A MAGNETIC-AMPLIFIER REGULATED D.-C. POWER SUPPLY CONNECTED TO SAID A.-C. POWER INPUT POWER FOR PROVIDING REGULATED DIRECT CURRENT FROM SAID UNREGULATED A.-C. INPUT POWER, CYCLICALLY SWITCHED INVERTER MEANS HAVING A PAIR OF INPUT TERMINALS CONNECTED TO THE OUTPUT OF SAID D.C-C. POWER SUPPLY AND APLURALITY OF OUTPUT TERMINALS FROM WHICH IS PROVIDED POLYPHASE ALTERNATING CURRENT FROM SAID REGULATED DIRECT CURRENT, A SOURCE OF FIXED FREQUENCY PULSES CONNECTED WITH SAID INVERTER MEANS FOR CONTROLLING THE SWITCHING RATE OF SAID INVERTER MEANS AND THEREBY REGULATE THE FREQUENCY OF THE POLYPHASE ALTERNATING CURRENT FROM SAID INVERTER MEANS, RECTIFIER MEANS CONNECTED TO SAID OUTPUT TERMINALS FOR DERIVING A D.-C. CONTROL VOLTAGE FROM ONE PHASE OF SAID ALTERNATING CURRENT OUTPUT FROM SAID INVERTER MEANS, AND MEANS CONNECTING SAID D.-C. CONTROL VOLTAGE TO SAID MAGNETIC-AMPLIFIER REGULATE D.-C. POWER SUPPY FOR CONTROLLING THE AMPLITUDE OF THE DIRECT CURRENT FROM SAID MAGNETIC-AMPLIFIER D.-C. POWER SUPPLY AND THEREBY REGULATE THE AMPLITIDUE OF SAID POLYPHASE A.-C. OUTPUT POWER AT SAID OUTPUT TERMINALS.
