Abstract

UN SISTEMA DE CONTROL PARA ENERGIA LLEVADA A UNA CARGA INDUCTIVA INCLUYE LA CAPACIDAD DE COMPARTIR UNA SOLA FUENTE (16) INVERSORA DE ENERGIA ENTRE NUMEROSAS CARGAS (10) INDUCTIVAS. LAS NUMEROSAS CARGAS INDUCTIVAS PUEDEN TENER DIFERENTES FRECUENCIAS DE RESONANCIA. EL SISTEMA DE CONTROL PROVOCA QUE UNA CANTIDAD PRESELECCIONADA DE ENERGIA SEA RETIRADA DE LA FUENTE DE ENERGIA INVERSORA Y LLEVADA A LAS CARGAS DE UNA MANERA TEMPORAL COMPARTIDA. EL SISTEMA DE CONTROL MODIFICA LA ELEVACION DE FASE ENTRE VOLTAJE DE CARGA Y CORRIENTE DE CARGA Y AJUSTA SELECTIVAMENTE LA CANTIDAD DE VARIACION COMO RESPUESTA A UN EXCESO O UN DEFECTO DE ENERGIA RETIRADA DEL INVERSOR Y LLEVADA A LA CARGA QUE PUDIERAN OCURRIR CUANDO SE CONMUTA ENTRE CARGAS.
