A SYSTEM FOR CONTROLLING THE OUTPUT VOLTAGE OF AN ELECTRICAL POWER COVERTER COMPRISING: A SOURCE OF ELECTRICAL ENERGY, AUXILIARY MEANS POWERED BY ENERGY FROM THE SOURCE FOR PRODUCING A UNIDIRECTIONAL ELETRICAL OUTPUT, A POWER CONVERTER POWERED BY ENERGY FROM THE SOURCE AND BY THE AUXILIARY MEANS OUTPUT FOR PRODUCING AN OUTPUT FOR A LOAD, AND MEANS CONNECTED TO CONTROL THE AUXILIARY MEANS AND CONNECTED TO RECEIVE THE POWER CONVERTER OUTPUT FOR MAKING THE AUXILIARY MEANS OPERATIVE WHEN THE CONVERTER OUTPUT VOLTAGE IS LESS THAN A PREDETERMINED VOLTAGE AND FOR CYCLICALLY VARYING THE AUXILIARY MEANS OUTPUT VOLTAGE SUBSTANTIALLY IN PHASE WITH THE POWER CONVERTER OUTPUT VOLTAGE AS A FUNCTION OF THE DIFFERENCE BETWEEN THE POWER CONVERTER OUTPUT VOLTAGE AND SAID PREDETERMINED VOLTAGE.
