Abstract

Un convertidor DC-DC resonante utilizado para accionar un montaje LED incluye un convertidor de medio puente configurado para recibir la energía de entrada DC y producir un voltaje de onda cuadrada. Un circuito de tanque resonante que incluye un elemento inductivo, un primer capacitor de resonancia y un segundo capacitor de resonancia, está acoplado con el convertidor de medio puente para recibir el voltaje de onda cuadrada, de modo que se produce un voltaje AC sinusoidal a través del segundo capacitor de resonancia. Un transformador de salida con un arrollamiento primario y uno o más arrollamientos secundarios, está acoplado en paralelo con el segundo capacitor de resonancia y un circuito de corte está acoplado con el arrollamiento primario, de modo que el voltaje a través del arrollamiento primario no excede sustancialmente el voltaje de la energía de entrada DC. Un rectificador de salida está acoplado con uno o más arrollamientos secundarios del transformador de salida y está configurado para producir un voltaje de salida generalmente de DC.
