Abstract

Se presenta un convertidor bidireccional CA-CD con tamaño de componente pasivo e interferencia electromagnética de modo común reducidos. El convertidor incluye una etapa de entrada mejorada formada por dos inductores diferenciales acoplados, dos inductores comunes y diferenciales acoplados, un capacitor y dos capacitores de modo común. Con esta estructura de entrada, el volumen, peso y costo de la etapa de entrada puede reducirse en gran medida. Adicionalmente el rizado de corriente de entrada e interferencia electromagnética de modo común pueden atenuarse en gran medida, de modo que se puede adoptar una frecuencia de interruptor menor para lograr mayor eficiencia.
