Patent number: 9787211Abstract: An AC power converter converts power from an AC power source to an AC load. A DC power holding source is coupled to an input half-bridge switch, a common half-bridge switch and an output half-bridge switch. A controller is coupled to at least two of the input half-bridge switch, the common half-bridge switch, and an output half-bridge switch. The controller switches the input half bridge at the first switching frequency in boost mode and at the line frequency in buck mode. The controller also switches the output half bridge switch at the first switching frequency in buck mode and at the line frequency in boost mode. Input and output low pass filters can eliminate switching frequency energy from entering the AC source and load. The converter maintains a DC power holding source voltage slightly above peak AC input voltage and significantly less than twice the peak AC input voltage.Type: GrantFiled: October 7, 2016Date of Patent: October 10, 2017Assignee: TSi Power Corp.Inventors: Robert S Schneider, Pallab Midya, Peter Nystrom

Patent number: 9768705Abstract: An AC power converter converts power from an AC power source to an AC load. A DC power holding source is coupled to an input half-bridge switch, a common half-bridge switch and an output half-bridge switch. A controller is coupled to the input half-bridge switch, the common half-bridge switch, and an output half-bridge switch to generate at least two control signals at a common switching frequency, wherein the controller generates the at least two control signals with a phase difference there between chosen to cause a ripple frequency in both the input low pass filter and the output low pass filter to be double the common switching frequency. An input low pass filter can eliminate switching frequency energy from entering the AC power source. An output low pass filter can eliminate switching frequency energy from entering the AC load.Type: GrantFiled: October 7, 2016Date of Patent: September 19, 2017Assignee: TSi Power Corp.Inventors: Pallab Midya, Robert S Schneider, Peter Nystrom

Patent number: 6540315Abstract: System and methods for using a fluid ejection system to distribute fluid drop density of a region between at least two overlapping swaths having pixels on a receiving medium. Using the method, overlapping swaths are stitched together by distributing a fluid ejection pattern between the overlapping swaths within the overlapped region. Because small drops of fluid can be distributed within a single region, the fluid ejection pattern can be controlled and intermediate density regions can be created by distributing the fluid of drops within a region between two fluid ejector heads or between two swaths of the same fluid ejector head. The distribution can be linear or non-linear. Furthermore, overlapping swaths are stitched together by randomly varying a stitch location within the overlapped region. In this case, a stitch location is randomly varied in the slow scan direction.Type: GrantFiled: January 16, 2002Date of Patent: April 1, 2003Assignee: Xerox CorporationInventors: Peter Nystrom, Mark Cellura, John Walsh
