hi...i built the 3-level diode clamped inverter on pspice to study THD...now i am using the vpulse modulator and i am varying the number of pulses ..i put 10,20 and 40 pulses and the THD is only varying with 0.2% from 10 to 40 pulses ...so; i want to know if this is a good result and resonable change and weather it should change with more deviation from 10 to 40 pulses...moreover what is the optimal number of pulses to be used to get the best THD...thx
Added after 18 minutes:
i need to tell that when i used number of pulses =100 the total harmonic distortion is 0.06% greater than that when the number of pulses is 40 only...is that sound logic?...is there the optimal number of pulses is between these two values which are the 40 nd 100 pulses....or what i am talking is not logic at all...is the right logic?::: the more number of pulses we use; the best and lowest THD we get???[/b]
