This paper provides a comprehensive analysis, including static, dynamic, and experimental validation, of a voltage-doubler Ćuk rectifier operating in the discontinuous conduction mode (DCM) for singlephase applications. The proposed topology integrates two classic Ćuk rectifiers through a three-position switch, allowing for either a doubled output voltage or reduced voltage efforts compared to the conventional topology. The voltage gain is increased while maintaining the step-up/step-down characteristic of the Ćuk family and power components are activated only in a half-cycle of the electrical grid, thus reducing the current efforts in the semiconductors. These features make the Ćuk converter suitable for higher voltage applications. The proposed topology is analyzed in DCM, where a high power factor is naturally achieved without a current control loop. An experimental prototype of 1 kW is built to verify the theoretical analysis, and the results show an efficiency of 94.68% with an input current THD of 1.86% ate rated power, including an output voltage control loop. Furthermore, the proposed topology is compared to the conventional Ćuk rectifier, both operating in DCM and with power factor correction (PFC).

Resumo-Este artigo apresenta a análise estática, dinâmica e a validação experimental de um retificadoŕ Cuk monofásico dobrador de tensão operando no modo de condução descontínuo (MCD). A topologia proposta integra dois retificadoresĆuk clássicos através de um interruptor de três posições, o que dobra a tensão de saída ou reduz os esforços de tensão em relação à topologia clássica. A estrutura aumenta o ganho de tensão, mantendo a característica abaixadora/elevadora da famíliaĆuk. Além disto, parte dos componentes de potência são acionados somente em meio ciclo da rede elétrica, o que também reduz esforços de corrente nos semicondutores. Essas características permitem aumentar os níveis de potência e de tensão de operação do conversoŕ Cuk. A topologia proposta foi analisada no MCD, modo no qual o alto fator de potência é naturalmente obtido sem a necessidade de uma malha de controle de corrente. De modo a corroborar a análise teórica desenvolvida, foi construído um protótipo em laboratório de 1 kW, com tensão eficaz de entrada de 220 V, tensão de saída de 400 V e frequência de comutação de 50 kHz. São apresentados resultados experimentais com malha de controle da tensão de saída, sendo que, em potência nominal, o retificadoŕ Cuk dobrador de tensão atingiu um rendimento de 94,68% e uma corrente de entrada com THD de 1,86%.
