A neural network controlled optimal pulse-width modulated STATCOM

Abstract

The paper describes a technique to control the harmonic output of a static synchronous compensator (STATCOM) using a pulse width modulation (PWM) scheme with a minimal number of additional switchings. A neural network algorithm is developed to define the switching instants. This technique offers an alternative to the multi-pulse techniques that require complex magnetic circuit arrangements as well as to the conventional PWM technology that requires a large number of switchings.
