Abstract

UN METODO PARA CONTROLAR UN INVERSOR TRIFASICO DE TRES NIVELES COMPRENDE LOS PASOS DE: JUZGAR SI LA CORRIENTE DEL TERMINAL DE SALIDA DE UN INVERSOR DE LA FASE, DE TAL FORMA QUE EL POTENCIAL ELECTRICO DEL TERMINAL DE SALIDA IGUALE EL TERMINAL DE PUNTO NEUTRO DEL CONDENSADOR ENTRE LOS TERMINALES DE TRES SALIDAS DEL INVERSOR, ESTA EN UNA DIRECCION POSITIVA EN LA QUE LA CORRIENTE FLUYE HACIA UNA CARGA CONECTADA A ESTE TERMINAL DE SALIDA, O EN UNA DIRECCION NEGATIVA EN LA QUE LA CORRIENTE FLUYE DESDE LA CARGA CUANDO EXISTE OTRO MODO DE CONEXION Y DESCONEXION CON EL MISMO VECTOR DE VOLTAJE DE ESPACIO INSTANTANEO QUE EL VECTOR DE VOLTAJE DE ESPACIO INSTANTANEO EN UN MODO DE CONEXION Y DESCONEXION SELECCIONADO PROVISIONALMENTE; SELECCIONAR DEFINITIVAMENTE EL MODO DE CONEXION Y DESCONEXION SELECCIONADO PROVISIONALMENTE SI EL RESULTADO DE LA ESTIMACION ES POSITIVO Y SELECCIONAR DEFINITIVAMENTE OTRO MODO DE CONEXION Y DESCONEXION EN LUGAR DEL MODO DE CONEXION Y DESCONEXION SELECCIONADO PROVISIONALMENTE CUANDO EL RESULTADO DE LA ESTIMACION ES NEGATIVO EN EL CASO DE QUE EL POTENCIAL ELECTRICO DEL TERMINAL DE PUNTO NEUTRO DEL CONDENSADOR ESTE POR ENCIMA DE UN VALOR DE LIMITE SUPERIOR PRESELECCIONADO; Y SELECCIONAR DEFINITIVAMENTE EL MODO DE CONEXION Y DESCONEXION SELECCIONADO PROVISIONALMENTE SI EL RESULTADO DE LA ESTIMACION ES NEGATIVO Y SELECCIONAR DEFINITIVAMENTE OTRO MODO DE CONEXION Y DESCONEXION EN LUGAR DEL MODO DE CONEXION Y DESCONEXION SELECCIONADO PROVISIONALMENTE CUANDO EL RESULTADO DE LA ESTIMACION ES POSITIVO EN EL CASO DE QUE EL POTENCIAL ELECTRICO DEL TERMINAL DE PUNTO NEUTRO DEL CONDENSADOR ESTE POR DEBAJO DE UN VALOR DE LIMITE INFERIOR PRESELECCIONADO.
