LOSS COMPARISON OF TWO AND THREE-LEVEL INVERTER
In this paper, expressions for switching and conduction losses in the four inverter topologies are reviewed. Analytical expression for DC-link capacitor losses are derived for the two
DC Losses: This happens due to resistance in cables before inverter conversion. Inverter (Power Limitation) Losses: Occur when generated power exceeds inverter capacity. Inverter (DC/AC Conversion) Losses: Result from inefficiencies during DC to AC conversion. Auxiliary Losses: Come from self-consumption by auxiliary equipment.
Inverter (DC/AC Conversion) Losses: Result from inefficiencies during DC to AC conversion. Auxiliary Losses: Come from self-consumption by auxiliary equipment. AC Cable Losses (LV): Occur due to resistance in low-voltage cables as current flows from the inverter. TR Losses (LV/MV): Losses caused by transformation from low to medium voltages.
Suppose the efficiency of the inverter is 90 percent, then 10 percent of the power is lost in the inverter. It depends on the load as to how efficient the inverter will be. Generally speaking, it is usually at its peak at about two-thirds of the capacity of the inverter.
If an inverter's efficiency is 90%, it loses 10% of the input energy. Module degradation is assessed through lab testing or operational data. Choosing high-quality PV modules reduces this type of loss. Angle losses depend on solar angles and module tilt. Specialized PV simulation software can model light incidence and calculate these losses.
