Claim 1

A SYSTEM FOR ELIMINATING RIPPLE IN A VOLTAGE SUPPLIED FROM A SOURCE TO A LOAD COMPRISING: SWITCHING MEANS BETWEEN SAID SOURCE AND SAID LOAD FOR PERIODICALLY INTERUUPING SAID VOLTAGE; MEANS BETWEEN SAID SWITCHING MEANS AND LOAD FOR SMOOTHING THE VOLTAGE OUTPUT OF SAID SWITCH; GENERATING MEANS RESPONSIVE TO SAID SMOOTHED VOLTAGE OUTPUT FOR PROVIDING A REFERENCE SIGNAL; A FREE-RUNNING MULTIVIBRATOR GENERATING PULSES AT A SUBTIANTIALLY CONSTANT REPETITION RATE; A BISTABLE MULTIVIBRATOR COUPLED TO THE OUTPUT OF SAID FREE-RUNNING MULTIVIBRATOR; MEANS COUPLING THE OUTPUT OF ONE STAGE OF SAID BISTABLE MULTIVIBRATOR TO SAID SWITCHING MEANS FOR CONTROLLING SAID SWITCHING MEANS; AND A FEEDBACK CIRCUIT FROM BETWEEN THE OUTPUT OF SAID SWITCHING MEANS AND THE OTHER STAGE OF SAID BISTABLE MULTIVIBRATOR INCLUDING MEANS FO R INTEGRATING THE OUTPUT OF SAID SWITCHING MEANS AND DETECTING WHEN THE MAGNITUDE OF SAID INTEGRATED OUTPUT EXCEEDS THE MAGNITUDE OF SAID REFERENECE SIGNAL, THEN PRODUCING A SIGNAL FOR PRESETTING SAID BISTABLE MULTIVIBRATOR, THEREBY CONTROLLING THE INTERVAL OF PULSES APPLIED TO SAID SWITCHING MEANS.
