Three Phase Inverter With Reduce Number of Switches

Abstract

The main objective of this paper is to reduce the number of power electronics components by using the
novel topology of multilevel inverter.to reduce number of switches as increased the level of inverter the number of
switches should be reduce as per the different calculation of components. In the industrial application on the basis of
drives the multilevel inverter can do great job to get desired output. But in the conventional multilevel inverter use of
power electronics components are more as compare to unconventional or proposed topology of multilevel inverter.
The proposed multilevel inverter use only 16 switches for 5-level and as increased the level the level the number of
switches will reduced. As using the novel topology with help of Selective Harmonics Elimination (SHE) technique for
give the triggering pulse to the switches. By using this PWM method the lower order harmonics will reduced
gradually.
