Publication number: 20100327963Abstract: An active snubber operates, in part, to compel switching components, such as switch-mode power supplies and converters, to attain desired values rapidly, albeit temporarily, during which time there is sufficient time for a power supply's internal regulation system to sustain these values independently. The invention can dampen ringing, accelerate response time, and correct erroneous responses of the output of the switching converter. In one embodiment, the active snubber, which is operably connected to the output of a switching component that has a switching or ringing frequency, f1, and that is modulated by a signal generator at a frequency, f2, is characterized by an operable connection to the output of a buffer connected to the signal generator. The buffer provides a reference voltage that is equal to the switching component output voltage at the modulation frequency at f2.Type: ApplicationFiled: April 9, 2010Publication date: December 30, 2010Applicant: BATTELLE MEMORIAL INSTITUTEInventor: Matthew S.

Publication number: 20100329293Abstract: Improved current controllers of the present invention provide efficient, low noise, precision current control for devices having such operational requirements. The current controllers are characterized by a PWM regulator operably connected to a linear regulator. The PWM regulator regulates a voltage drop across the linear regulator, wherein the voltage provided to the linear regulator is greater than the output voltage of the linear regulator by a controlled operating margin. The PWM provides efficient power conversion and minimizes waste power dissipation in the linear regulator. The linear regulator, in turn, provides low noise, precision current drive to the connected load.Type: ApplicationFiled: June 26, 2009Publication date: December 30, 2010Applicant: BATTELLE MEMORIAL INSTITUTEInventor: Matthew S.
