DC to AC Converters Inverters - Engineering
www.site.uottawa.caOutput of the inverter is “chopped AC voltage with zero DC component”. It contain harmonics. An LC section low-pass filter is normally fitted at the inverter output to reduce the high frequency harmonics. In some applications such as UPS, “high purity” sine wave output is required. Good filtering is a must.

It does not need output transformer like parallel inverter. It sometimes called center-tapped source inverter. The basic configuration of this inverter is shown in Fig 14.1.
CHAPTER4 MODEL OF THREE-PHASE INVERTER
www.tntech.eduThe dc to ac converters more commonly known as inverters, depending on the type of the supply source and the related topology of the power circuit, are classified as voltage source inverters (VSIs) and current source inverters (CSIs). The single-phase inverters and the switching patterns were discussed elaborately in Chapter two
