Buck-boost voltage regulation circuit
Abstract
Abstract THE INVENTION RELATES TO A BUCK-BOOST VOLTAGE REGULATOR WHEREIN THE OUTPUT OF A DC VOLTAGE SOURCE TO BE CONTROLLED IS COMBINED WITH A SOURCE OF ALTERNATING CURRENT FROM AN INVERTER. THE RESULTANT SIGNAL IS APPLIED TO A CHOPPER CIRCUIT. THE CHOPPER CIRCUIT UTILIZES A PAIR OF SWITCHING TRANSISTORS ALTERNATELY MAINTAINED IN CONDUCTION BY A SINGLE CURRENT TRANSFORMER AND AN INDUCTIVE LOAD. THE CHOPPER CIRCUIT IS DESIGNED TO PERMIT INSTANTANEOUS SWITCHING BETWEEN THE TRANSISTORS AND IS FURTHER DESIGNED TO PREVENT SIMULTANEOUS CONDUCTION THEREOF. THIS ALLOWS OPERATION OF THE CHOPPER CIRCUIT THROUGH A WIDE RANGE OF FREQUENCIES WITHOUT ANY LONG COMMUTATION INTERVALS AND THEREBY PREVENTS SHORT CIRCUITS FROM BEING APPLIED THROUGH THE TRANSFORMER TO THE INVERTER.
