Zustand: Hervorragend | Sprache: Englisch | Produktart: Bücher | Multi level inverters are used to control electric drive of hybrid electric vehicle (HEV) of high power and they enhances drives performance, as they can generate sinusoidal voltages with only fundamental switching frequency. Hybrid Electric Vehicle is an emerging technology because of the fact that it avoids environmental pollution and increases vehicles fuel efficiency.The multilevel voltage source inverters with unique structure allow them to reach high voltages with low harmonics without the use of transformers or series-connected synchronized switching devices.The general function of the multilevel inverter is to synthesize a desired voltage from several levels of dc voltages. For this reason, multilevel inverters can easily provide the high power required of a large electric drive. As the number of levels increases, the synthesized output waveform has more steps, which produces a staircase wave that approaches a desired waveform. Also, as more steps are added to the waveform.…
