Abstract

GENERACION DE UNA ONDA DE REFERENCIA PARA CONTROL DE DISPARO DE TIRISTORES EN CONVERTIDORES ESTATICOS DE CORRIENTE. CONSISTE EN DERIVAR ONDAS DE REFERENCIA DE ANGULO PARA PASO POR COMPUERTA POR MEDIO DE UN GENERADOR DE IMPULSOS (3), UTILIZANDO UNA SOLA SEÑAL COMUN DE CONTROL DE VOLTAJE VARIABLE (11) Y UN COMPARADOR (4) PARA APLICAR LAS DIVERSAS SEÑALES DE PASO POR COMPUERTA A LOS CIRCUITOS MULTIPLEXADORES Y EXCITADORES DE LOS TIRISTORES. UNA PLURALIDAD DE INTERRUPTORES, CONTROLADOS POR EL CIRCUITO DE LOGICA DE DISPARO, ESTABLECE EL ORDEN DE SELECCION ENTRE LAS ONDAS DE REFERENCIA COSENOIDALES QUE SE VAN A GENERAR.
