NOVELTY - The system has a single stage direct current (DC) to alternating current (AC) voltage conversion circuitry containing a set of three phase AC inverter circuits electrically connected to a common three-phase AC output. Each inverter circuit receives bipolar DC voltage supplied from respective set of concentrated photovoltaic (CPV) modules in a solar array, and supplies power to a common AC output. A set of CPV cells is contained and connected electrically in series in each CPV module. A bypass diode is electrically in parallel with each CPV cell.    USE - Apparatus for converting DC voltage to AC voltage in a photovoltaic system i.e. three phase AC photovoltaic electrical power generation system.    ADVANTAGE - The inverter circuit receives the bipolar DC input voltage level that is high enough to directly convert to the AC working voltage level, and provides a three-phase 480V AC output voltage level from the inverter circuit without the DC input boost stage or a step up transformer after an inverter portion, thus avoiding the need for supplemental input DC voltage level boosting strategies such as DC input boost stage, and increasing the DC input voltage level to a higher DC voltage level for DC to AC conversion. The inverter circuits are contained in respective sub assemblies with connections that are easily coupled to or slid into the electrical connections, thus enabling replacement, troubleshooting, and easy servicing of the inverter circuits. The wiring is installed and connections are made between the CPV cells in each CPV module in a manufacturing facility, thus eliminating individually wiring each CPV cell in solar array during field installation of the solar array. The inverter circuit has a pulse modulated switching circuit that generates continuous three-phase power to avoid need for large capacitance value electrolytic capacitors, eliminates the electrolytic capacitor in the DC link of the inverter and uses film based capacitors due to overall lower need for capacitance in the inverter circuit, thus reducing power conversion equipment cost and improving efficiency and reliability of the system.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for converting DC voltage to AC voltage in a three phase AC photovoltaic system.    DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view showing shading effects of CPV modules of solar arrays from sunrise to sunset and at various angles of the Sun in between sunrise to sunset.
