Este artigo apresenta um controlador discreto para o retificador boost três níveis com fator de potência corrigido. Modelos discretos lineares de primeira ordem para ambas as malhas de tensão e corrente são apresentadas. Controladores servos com realimentação de estados são utilizados, sendo projetados utilizando-se um regulador linear quadrático discreto. Além disto, um observador de estados preditivo é utilizado para compensar o tempo de atraso associado à implementação em processadores digitais. É apresentada uma descrição detalhada da lógica de comando que garante a divisão simétrica de tensão do barramento cc. Resultados experimentais de um retificador de 1.5kW são apresentados para validar a análise desenvolvida bem como para demonstrar a boa performance do sistema.
