Description

 In this project using of a newly voltage balancing NNPC inverter had been developed. This output is utilized in the transportation industry to adopt the multilevel inverter-based propulsion systems. In this proposed work space vector pulse width modulation (SVPWM) technique is used, this technique is very efficient and eliminate unwanted harmonics from the output voltage over than other PWM technique. This PWM method is easy to implement and a very few reckoning.  This inverter module having back-to-back clamped diode, voltage modulation operation thus achieve a voltage regulation and high efficiency at any loading condition. Multilevel inverters are very popular in medium-voltage power conversion  such as motor drives, power conditioning devices, renewable energy generation and distribution because of low voltage stress on switching devices, better harmonic reduction, low switching frequency, and less switching losses. Due to the presence of these elements the inverter can operate normally and the voltage stress is shared uniformly to all switching devices and capacitor voltage should be controlled. Thus results overabundance of switching states. The cogency and expediency results of the proposed topology is verified by simulation. That inverter design is help to reduce the harmonic in normal and that result was analysis in MATLAB Simulink model
