Figure 2-2 Schematic Diagram of the 100/125kW Inverter
The input from PV source circuits passes through surge protection circuitry,
DC EMI wave filter, to bus capacitance. The inverter then converts the DC
voltage to 3-phase AC voltage. Most of the high frequency AC harmonics are
removed with a wave filter. The output AC is connected to the grid via two-stage
relay. There is also a three-phase SPD at the AC output side.
