Patent number: 11563379Abstract: This disclosure describes systems, methods, and apparatus for reducing current imbalances between phases in a multi-phase converter as well as reducing instances of particular phases switching twice within a single pulse-width modulated cycle, or other time period. Phases that have not switched for a longest period of time can be compared to see if swapping their firing patterns would reduce current imbalances, and if so, then those firing patterns can be swapped.Type: GrantFiled: May 3, 2021Date of Patent: January 24, 2023Assignee: Advanced Energy Industries, Inc.Inventor: Daryl Frost

Patent number: 9042121Abstract: Among many embodiments, a power conversion apparatus and a method for converting power are disclosed. The power conversion apparatus may include switching components configured to create an alternating current; a preemptive detector arranged and configured to provide, in advance of the alternating current reaching a zero-crossing, a control signal responsive to the alternating electrical current approaching the zero-crossing; and a controller configured, at least in part, to change a state of the switching components before the zero crossing, in response to the control signal.Type: GrantFiled: February 4, 2013Date of Patent: May 26, 2015Assignee: Advanced Energy Industries, Inc.Inventors: Hendrik Walde, Daryl Frost

Patent number: 8044594Abstract: One embodiment comprises a plasma processing system having a plasma chamber, a generator, a feedback component, and a controller. The feedback component is adapted to receive at least one first signal having a level dependent upon the power signal supplied from the generator to the chamber. A feedback output is adapted to emit a second signal to the controller, which is adapted to supply a third signal to the power generator. The third signal is configured to control the power generator to supply the power signal at a power level for a particular processing application. The power generator is further controlled by the controller to one of reduce and remove power from the plasma processing chamber and subsequently increase the voltage level until the power level reaches a threshold level. The power generator is further controlled to subsequently modulate the voltage until the voltage returns to a first voltage level.Type: GrantFiled: April 15, 2009Date of Patent: October 25, 2011Assignee: Advanced Energy Industries, Inc.Inventors: Forrest Morgan, Daryl Frost, Frank Heine, Doug Pelleymounter, Hendrik Walde
