Abstract
CIRCUITO DE PROTECCION PARA UN CIRCUITO ONDULADOR. EN FUNCION DE LA MAGNITUD DE LA TENSION APLICADA AL CIRCUITO DE CARGA CONECTADO A LA SALIDA CONMUTADA DEL ONDULADOR, SE PUEDE CONECTAR UNA REACTANCIA (DR) EN PARALELO A POR LO MENOS UNO DE LOS ARROLLAMIENTOS SECUNDARIOS (T2) DEL TRANSFORMADOR, A TRAVES DE UNOS CONMUTADORES EN FUNCION DE LA TENSION, PREFERENTEMENTE A TRAVES DE UN TIRISTOR (12) A LA FASE (V-) DE LA TENSION CONTINUA QUE ALIMENTA EL POTENCIAL MAS BAJO DEL ONDULADOR. LA CORRIENTE DE RETENCION PARA EL TIRISTOR QUE TIENE CONTINUIDAD (12), SE TOMA DEL CIRCUITO DE CONTROL DE UN CONMUTADOR ELECTRONICO (S2). DE APLICACION EN LAMPARAS DE DESCARGA DE GAS.
