A THREE-PHASE GENERATOR COMPRISING THREE AMPLIFIERR UNITS, EACH OF SAID UNITS HAVING AN INPUT AND AN OUTPUT MEANS TO APPLY A COMMON ALTERNATING CURRENT SOURCE TO EACH OF THE INPUTS, MEANS IN EACH OF SAID AMPLIFIERS TO PROVIDE A SIGNAL ACROSS SAID OUTPUT OF FREQUENCY SUBSTANTIALLY EQUAL TO ONE-THIRD THAT OF THE APPLIED FREQUENCY, EACH OF SAID AMMPLIFIER UNIS HAVING AN ADDITIONAL OUTPUT ACROSS WHICH TTHE DIVIDED FREQUENCY SIGNAL APPEARS, MEANS CONNECTING SAID THREE ADDITIONAL OUTPUTS IN SERIES TO DEFINE A CLOSED LOOP, AN INDUCTANCE OF THE SATUURATED TYPE IN SAID LOOP THAT WILL PRESENT A HIGH RESISTANCE WHEN THE SUMM OF THE ALTERNATING CURRENT VOLTAGES FROM THE ADDITIONAL OUTPUTS OF EACH OF THE UNITS IS EIQUAL TO THE APPLIED INPUT FREQUENCY TO TTHE THREE UNITS AND WHICH WILL PRESENT A LOW RESISTANCE WHEN THE SUM OF SUCH ALTERNATING CURRENT VOLTAGES IS LESS THAN SUCH INNNPUT FREQUENCY, THE CURRENT FREQUENCY IS LESS THAN SUCH INPUT FREQUENCY, THE CURRENT DRAWNN THROUGH SAID SERIES CONNECTED ADDITIONAL OUTPUTS WILL BE SUBSTANTIALLY INCREASED TO OVERLOAD EACH OF SAID AMPLIFIER UNITS, EACH OF SAID AMPLIFIERS HAVING ASSOCIATED AMPLIFIER TRANSISTORS, SAID TRANSISTORS HAVING A MAXIMUM CURRENT OUTPUT CAPABILITY BELOW THAT OF THE CURRENT LOAD CAUSED WHEN THE COMBINED OUTPUT FREQUENCY DEVIATES FROM THE INPUT FREQUENCY, WHEREBY SAID TR ANSISTORS WILL OPERATE RANDOMLY UNTIL THE SUM OF THE OUTPUT FREQUENCY VOLTAGES IS EQUAL TO THE INNPUT FREQUENCY VOLTAGE.
