Patent ID: 6940040

Claim:
A power supply system for creating a first AC signal and a second AC signal, said system comprising: a first system for creating said first AC signal with at least two power supplies operated at a first synchronized time determined by a first synchronized signal with first operation parameters and a high accuracy interconnection interface between said power supplies of said first system to correlate polarity switching of said power supplies of said first system; wherein each power supply in said first system includes: a center tapped inductor with a first portion creating a first polarity where said first AC signal is positive and a second portion creating a second polarity where said first AC signal is negative; a first switch for routing said first AC signal through said first portion of said inductor; and a second switch for routing said first AC signal through said second portion of said inductor; and a second system for creating said second AC signal with at least two power supplies operated at a second synchronized time determined by a second synchronize signal offset from said first synchronize signal with second operation parameters and a high accuracy interconnection interface between said power supplies of said second system to correlate polarity switching of said power supplies of said second system; wherein each power supply in said second system includes: a center tapped inductor with a first portion creating a first polarity where said second AC signal is positive and a second portion creating a second polarity where said second AC signal is negative; a first switch for routing said second AC signal through said first portion of said inductor; and a second switch for routing said second AC signal through said second portion of said inductor.
