This paper addresses the timely issue of analyzing the custom power controllers based on an improved Pulse-Width Modulation (PWM) technique called the Inverted - Sine PWM (ISPWM). These controllers are also named as Distribution - Flexible AC Transmission System (DFACTS). DFACTS are a new generation of power electronics based equipment aimed to enhance the reliability and quality of power flow in low-voltage distribution networks. The proposed ISPWM technique can be used to control Voltage Source Converters (VSC) of custom power devices. This switching technique uses a sinusoidal reference signal and an inverted-sine as carrier signal. The ISPWM technique generates low voltage Total Harmonic Distortion (THD) in comparison with conventional Sinusoidal Pulse Width Modulation (SPWM) technique. This type of switching technique called the ISPWM has been used on a simple VSC for analyzing its impact.

Abstract
This paper addresses the timely issue of analyzing the custom power controllers based on an improved Pulse-Width Modulation (PWM) technique called the Inverted - Sine PWM (ISPWM). These controllers are also named as Distribution - Flexible AC Transmission System (DFACTS). DFACTS are a new generation of power electronics based equipment aimed to enhance the reliability and quality of power flow in low-voltage distribution networks. The proposed ISPWM technique can be used to control Voltage Source Converters (VSC) of custom power devices. This switching technique uses a sinusoidal reference signal and an inverted-sine as carrier signal. The ISPWM technique generates low voltage Total Harmonic Distortion (THD) in comparison with conventional Sinusoidal Pulse Width Modulation (SPWM) technique. This type of switching technique called the ISPWM has been used on a simple VSC for analyzing its impact.
