  • Power conditioning system for a four quadrant photovoltaic array with an inverter for each array quadrant
    Patent number: 5896281
    Abstract: A photovoltaic (PV) power system having distributed square wave current DC to AC inverters integral with strings of PV cells in a PV array. The PV array is arranged into four quadrants and phase-shifted and summed AC voltages from each quadrant are further summed in a 12-phase to 3-phase transformer to produce a sinusoidal 3-phase AC voltage with a total harmonic distortion of less than 5 percent.
    Type: Grant
    Filed: July 2, 1997
    Date of Patent: April 20, 1999
    Assignee: Raytheon Company
