Space vector PWM for a two-phase VSI

International Journal of Electrical Power & Energy Systems, 2013
This paper proposes space vector pulse width modulation (SVPWM) technique to control a two-phase full bridge voltage source inverter (VSI) having reduced number of static switches with higher phase voltage output. SVPWM gives higher fundamental component amplitude, provides more efficient use of DC supply voltage and generates less harmonic distortion ...
