• Space vector pulse width modulation (SVPWM)
• Uninterruptible power supplies (UPS's)
• Voltage source inverter (VSI)

The rapid development of high switching frequency power electronics in the past decade leads towards wider application of voltage source inverters in AC power generation. Therefore, this prompts the need for a modulation technique with less total harmonic distortion, fewer switching losses, and wider linear modulation range. Space vector pulse width modulation (SVPWM) provides a better technique compared to the more commonly used PWM or sinusoidal PWM (SPWM) techniques because of their easier digital realization and better DC bus utilization. This paper aims to achieve two goals. One is to introduce an SVPWM technique based on a reduced computation method which is much simpler and faster than conventional means. The other is presenting a practical design and implementation of space vector PWM inverter based on a low cost microcontroller to overcome many of the issues experienced using the conventional methods.
