Actually, the inverter output voltage may have a harmonic content to a reasonable limit of 5%, one method of ensuring this is to insert filters between the load and the inverter. ... 6.10.1 Harmonic Reduction by Transformer Connections Output voltage from two or more inverters can be combined ... Figure 6.25(a) illustrates this principle using two transformers with series connected secondary windings.
