Two-level Voltage Source Inverter

2-level Voltage Source Inverter with Space Vector Modulation and Even-Order Harmonics Elimination.

Space Vector Pulse Width Modulation (SVPWM) is basically a modulation technique based on modulation of input dc signal (constant value) into output pulses of different width and different, usually 5 or 7, amplitude levels thus generating an AC signal which could be smooth out by proper filtering or selecting a proper inductive load. Space vector modulation scheme is superior to Pulse Width Modulation (PWM) scheme because there are two main problems in PWM, harmonic distortion and switching speed, and both of these problems are overcome by implementation of the SpaceVector PWM (SVPWM) technique.
One improved version of space vector modulation by using a modified two-level voltage source inverter for eliminating the even-order harmonics is also used.
