Power converter with regulated output

TLDR: In this article, the authors present an approach for regulating direct current power from an UNregulated direct Ccurrent power source to a PILOT OSCILLATOR and at least one STABILIZING UNIT.

Abstract: APPARATUS FOR REGULATING DIRECT CURRENT POWER FROM AN UNREGULATED DIRECT CURRENT POWER SOURCE COMPRISING A CONSTANT FREQUENCY PILOT OSCILLATOR AND AT LEAST ONE STABILIZING UNIT. EACH STABILIZING UNIT INCLUDES SWITCHING MEANS FOR INTERRUPTING THE CURRENT FROM THE DIRECT CURRENT POWER SOURCE DURING A PORTION OF EACH CYCLE WHICH IS CONTROLLED BY THE PILOT OSCILLATOR, AND INCLUDING A RECTIFYING CIRCUIT AND A FILTERING CIRCUIT FOR REFINING THE REGULATED OUTPUT FROM THE SWITCHING MEANS. THE OUTPUT OF THE FILTERING CIRCUIT IS MONITORED BY A COMPARISON DEVICE, WHICH GENERATES A SIGNAL, REPRESENTATIVE OF THE VARIATIONS OF THE OUTPUT VOLTAGE FROM A PREDETERMINED LEVEL AND, WHICH SIGNAL IS COUPLED TO AN ERROR SIGNAL GENERATOR TO PRODUCE AN ERROR SIGNAL. THE ERROR SIGNAL, WHICH IS REPRESENTATIVE OF THE OUTPUT OF THE COMPARISON DEVICE, AND THUS THE OUTPUT FROM THE FILTERING CIRCUIT IS THEN FED FROM THE ERROR SIGNAL GENERATOR TO AN ENAB LING DEVICE. THE ENABLING DEVICE GENERATES A SIGNAL TO CONTROL THE CONDUCTION AND NONCONDUCTION INTERVALS OF THE SWITCHING DEVICE, AS A FUNCTION OF THE VARIATION OF THE OUTPUT VOLTAGE FROM A PREDETERMINED VALUE.
