|
|
Recently Uninterruptible Power Supply (UPS) Systems are widely used in a variety of fields a s highily reliable power sources.
This paper presents the operation and performance of an UPS using sinusoidal Pulse Width Modulation techniques.
By using the sinusoidal PWM method for UPS systems, the property of harmonics, efficiency and distortion can be improved.
Experimental results showed that sinusoidal PWM techniques have good features for UPS system.
