US Patent:

8520413, Aug 27, 2013
Filed:

Aug 17, 2011
Appl. No.:

13/211892
Inventors:

Ken Tran - North Chelmsford MA, US
Feng Tian - Salem NH, US
Franklin Lee - Framingham MA, US
Wangbo Zhang - Winchester MA, US
Assignee:

MKS Instruments, Inc. - Andover MA
International Classification:

H02M 3/335
US Classification:

363 2103, 323222, 323271, 323287, 363 39
Abstract:

A power converter includes first and second circuit modules, a first capacitor, a second diode and a control module. The first circuit module includes a switching element in parallel with a first diode. The second circuit module includes a first inductor and the first circuit module. The inductor is in series with the first circuit module. The first capacitor is in parallel with the second circuit module. The second diode includes a first terminal and a second terminal, where the first terminal is in series with the second circuit module and the first capacitor, and the second terminal is coupled to a second power terminal. The control module varies one or more of the first capacitor and the first inductor based on at least one of a current of a load circuit or an input voltage. A resonating waveform is generated by a resonant circuit of the second circuit and is used by the control module to turn off the switching element under zero-current and zero-voltage conditions.

Abstract:

A method for controlling pulsed power that includes measuring a first pulse of power from a power amplifier to obtain data.

Compact, Configurable Power Supply For Energizing Ozone-Producing Cells

US Patent:

20130257301, Oct 3, 2013
Filed:

Mar 28, 2012
Appl. No.:

13/432415
Inventors:

Ken Tran - North Chelmsford MA, US
Feng Tian - Salem NH, US
Xing Chen - Lexington MA, US
Franklin Lee - Framingham MA, US
Assignee:

MKS INSTRUMENTS, INC. - Andover MA
International Classification:

H01J 37/248
US Classification:

315200 R
Abstract:

Improvements in the supply of high-frequency electrical power to ozone-producing cells can be accomplished using the systems and techniques described herein. Application of a DC-DC converter operating at a switching frequency substantially greater than a load frequency, supports generation of a high-voltage AC for powering such cells, while allowing for reductions in component size and reductions in a quality factor of a load tuning circuit. Controllable power inverters used in obtaining one or more of the switching and load frequencies can be controlled using feedback techniques to provide stable, high-quality power to ozone-producing cells under variations in one or more of externally supplied power and load conditions. An inrush protection circuit can also be provided to selectively introduce a current-limiting resistance until an input DC bus has been sufficiently initialized as determined by measurements obtained from the DC bus. The current limiting resistance can be a positive-temperature coefficient thermistor.
