View page

US Patent:

6556462, Apr 29, 2003

Filed:

Jun 28, 2002

Appl. No.:

10/064278

Inventors:

Robert Louis Steigerwald - Burnt Hills NY
Vinod John - Montpelier VT
Milan Zarko Ilic - Fort Collins CO

Assignee:

General Electric Company - Niskayuna NY

International Classification:

H02M 7217

US Classification:

363 89

Abstract:

A high power factor converter system comprises an input rectifier, a converter and a booster circuit. The input rectifier is configured for rectifying an input ac voltage. The converter is configured for generating an output voltage for the high power factor converter system. The converter comprises several converter switches and inverse parallel diodes. The booster circuit comprises an inductor and at least one converter switch and an inverse parallel diode of the converter. The inductor is coupled between the input rectifier and the converter. The booster circuit is configured for controlling the supply of a booster current through the inductor to be discontinuous when the instantaneous voltage level is less than a predetermined fraction of a dc voltage level across the converter and continuous when the instantaneous voltage level is greater than the predetermined fraction of the dc voltage level.

Apparatus And Method For Fast Arc Extinction With Early Shunting Of Arc Current In Plasma

View page

US Patent:

6943317, Sep 13, 2005

Filed:

Jul 2, 2004

Appl. No.:

10/884119

Inventors:

Milan Ilic - Fort Collins CO, US
Kalyan N. C. Siddabattula - Fort Collins CO, US
Andrey B. Malinin - Fort Collins CO, US

Assignee:

Advanced Energy Industries, Inc. - Fort Collins CO

International Classification:

B23K009/00

US Classification:

21912157, 21912159

Abstract:

There is provided by this invention a novel apparatus and method of operating a dc plasma process that diverts the power supply current from the plasma at the initiation of an arc, thereby inhibiting energy from flowing from the power supply to the plasma, and then to allow energy to flow again when the power supply re-enables energy flow to the plasma. The diverting means is connected to the output of the power supply to divert current away from the plasma at the initiation of an arc wherein the diverting means is actuated when the arc is detected on the output and diverts the current for a first pre-determined time. The diverting means is released at the end of the first pre-determined time before the current reaches zero wherein current is redirected to the plasma and the diverting means is reactivated at the end of a second pre-determined time in the event the arc is not extinguished.

Soft Switching Interleaved Power Converter

US Patent:

6979980, Dec 27, 2005

Filed:

Aug 24, 2004

Appl. No.:

10/925832

Inventors:

Bryce L. Hesterman - Fort Collins CO, US
Milan Ilic - Fort Collins CO, US
Andrey B. Malinin - Fort Collins CO, US
Kalyan N. C. Siddabattula - Fort Collins CO, US

Assignee:

Advanced Energy Industries, Inc. - Fort Collins CO

International Classification:

G05F001/656
G05F001/613

US Classification:

323222, 323274, 323284

Abstract:

There is provided by this invention soft switching interleaved power converters that are suitable for high power and high voltage applications such as plasma processing. They have greatly reduced switching losses and diode reverse-recovery losses which allows operation at high switching frequencies. The peak values of the reverse-recovery currents of the diodes are substantially less then their peak forward operating currents. The power converters incorporate power converter cells that comprise a plurality of switching assemblies that are operated with an interleaved switching pattern, and that are each connected to an input terminal of an inductor assembly that also has a common terminal. The inductance between each pair of input terminals is less than the inductance between each input terminal and the common terminal of the inductor assembly.

Dc-Dc Converter With Over-Voltage Protection Circuit

View page

US Patent:

7081598, Jul 25, 2006

Filed:

Aug 24, 2004

Appl. No.:

10/925830

Inventors:

Milan Ilic - Fort Collins CO, US
Vladislav V. Shilo - Fort Collins CO, US
Kalyan N. C. Siddabattula - Fort Collins CO, US

Assignee:

Advanced Energy Industries, Inc. - Fort Collins CO

International Classification:

B23K 9/00

US Classification:

21912159, 21912143

Abstract:

There is provided by this invention an apparatus and method of supplying to ignite a plasma wherein in the event of an arc a shunt switch is used to divert the power away from the plasma that is incorporated into an over-voltage protection circuit that controls the shunt switch to act as a boost switch when the arc is extinguished such that the stored inductor energy is used to boost the ignition voltage for reigniting the plasma if it is extinguished. When the arc is extinguished, the inductor current is diminished, and the plasma is ignited, then the switch S is turned OFF and the inductor energy goes to the plasma and the power supply operates in its normal operating mode.

US Patent:

7105075, Sep 12, 2006

Filed:

Jul 2, 2004

Appl. No.:

10/884027

Inventors:

Milan Ilic - Fort Collins CO, US
Kalyan N. C. Siddabattula - Fort Collins CO, US
David J. Christie - Fort Collins CO, US

Assignee:

Advanced Energy Industries, Inc. - Fort Collins CO

International Classification:

C23F 1/02
C23C 16/00

US Classification:

15634528, 15634524, 118723 E, 118723 I

Abstract:

There is provided by this invention an apparatus and method for controlling a dc magnetron plasma processing system that automatically adjusts the control signal to the power supply based upon the dynamic impedance of the load to control the output power to the plasma. The output voltage and the output current of the power supply that supplies power to the plasma is sampled over at a sampling frequency at least four to five times higher than the switching frequency and the dynamic impedance of the plasma is calculated based upon the sampled voltage and current from the algorithm.

Interleaved Soft Switching Bridge Power Converter

US Patent:

7423894, Sep 9, 2008

Filed:

Mar 3, 2006

Appl. No.:

11/367905

Inventors:

Milan Ilic - Fort Collins CO, US

Assignee:

Advanced Energy Industries, Inc. - Fort Collins CO

International Classification:

H02M 7/5387

Abstract:

An interleaved soft switching bridge power converter comprises switching poles operated in an interleaved manner so as to substantially reduce turn-on switching losses and diode reverse-recovery losses in the switching pole elements. Switching poles are arranged into bridge circuits that are operated so as to provide a desired voltage, current and/or power waveform to a load. By reducing switching turn on and diode reverse recovery losses, soft switching power converters of the invention may operate efficiently at higher switching frequencies. Soft switching power converters of the invention are well suited to high power and high voltage applications such as plasma processing, active rectifiers, distributed generation, motor drive inverters and class D power amplifiers.

Method And System For Conditioning A Vapor Deposition Target

View page

US Patent:

7445695, Nov 4, 2008

Filed:

Apr 28, 2006

Appl. No.:

11/413434

Inventors:

Milan Ilic - Fort Collins CO, US
Robert B. Huff - Fort Collins CO, US
George W. McDonough - Loveland CO, US

Assignee:

Advanced Energy Industries Inc. - Fort Collins CA

International Classification:

C23C 14/34

US Classification:

20419212, 20419213, 20429803, 20429808

Abstract:

A method and system for conditioning a vapor deposition target is described. In one illustrative embodiment, a vapor deposition system is operated in which a vapor deposition target is used, the occurrence of electrical arcs in the vapor deposition system is detected, and the vapor deposition target is conditioned by adjusting an output current of a power supply that powers the vapor deposition system and adjusting an interval during which energy is delivered to each arc to deliver substantially the same energy to each arc. In some embodiments, the energy delivered to each arc is approximately equal to the maximum energy that the vapor deposition target can withstand without being damaged. The described method and system significantly reduces the time required to remove impurities from a target and does not require the venting of the vacuum chamber or the removal of the target from the chamber.
