Inverters convert DC power into AC power through waves called either sine waves or modified sine waves. Sine waves are the waves that are typically found in power from a power plant. Modified sine waves are made to simulate sine waves. Inverters with modified sine waves work well for backup power in houses and are much less expensive. Although there are several types of inverters, all standard inverters use only one switch, or in other words, one power circuit.
Multilevel inverters are a a source of high power, often used in industrial applications and can use either sine or modified sine waves. Instead of using one converter to convert an AC current into a DC current, a multilevel inverter uses a series of semiconductor power converters (usually two to three) thus generating higher voltage. While with an inverter you would transfer energy with the flip of one switch, with a multilevel inverter you would have to flip several switches, each switch requiring a circuit. These multiple switches and circuits usually make multilevel inverters more expensive than inverters.

The various applications of multilevel inverters are 1. Motor Drives 2.Active Filters 3.Power conditioning
Types of Multilevel Inverter:Multilevel inverters are three types. 1.Diode clamped multilevel inverter 2.Flying capacitors multilevel inverter 3.Cascaded H- bridge multilevel inverter
The multi level inverter has been introduced since 1975 as alternative in high power and medium voltage situations. The Multi level inverter is like an inverter and it is used for industrial applications as alternative in high power and medium voltage situations. Multilevel inverters are three types. 1.Diode clamped multilevel inverter 2.Flying capacitors multilevel inverter 3.Cascaded H- bridge multilevel inverter
Advantages of Multilevel Inverter:The multilevel converter has a several advantages, that is:1. Common Mode Voltage: The multilevel inverters produce common mode voltage, reducing the stress of the motor and don't damage the motor.2. Input Current: Multilevel inverters can draw input current with low distortion3. Switching Frequency: The multilevel inverter can operate at both fundamental switching frequencies that are higher switching frequency and lower switching frequency. It should be noted that the lower switching frequency means lower switching loss and higher efficiency is achieved.4. Reduced harmonic distortion: Selective harmonic elimination technique along with the multi level topology results the total harmonic distortion becomes low in the output waveform without using any filter circuit.

One difference between a series and a parallel inverter is that series inverters are connected one after another. Whereas, parallel converters are only connected individually. Another difference between the two is that series inverters are used in small sub servers, whereas, parallel inverters are used in main servers.
The possessive form of the plural noun inverters is inverters'.

harmonics reduced due to multi switching and output is approximately sine wave so filter design and cost reduced.DC link voltage is also reduced because of splitted source.
Multilevel disc desiccation is a health condition of the spine. This health condition or disease is the loss of fluid between the discs of the spine. This fluid or jelly acts as cushion for the spine against pain. Multilevel disc desiccation is a degenarative disease.
Basically there are three types of inverters 1) Square wave Inverters 2) Quasi Square wave or Modified Square wave Inverters 3) True/Pure Sine wave Inverters The emerging trend among Inverters could be titled to Multi-Level Inverters which aim at the Increasing of Inverter Efficiency along with reduced Inverter Cost
