Abstract
A switching regulator having a solid state switch which turns on and off as needed to maintain output regulation, a choke which tries to maintain constant current flow, a voltage and current comparator which controls the solid state switch, and a flyback diode in series with an offset voltage which provides a current flow path for the choke when the solid state switch becomes non-conducting. The offset voltage results in a lower voltage across the diode and solid state switch when they are non-conducting. The offset control provides higher efficiencies with the most improvement at ultrasonic frequencies and higher voltages. Radio frequency interference is also significantly reduced.
