This paper describes a topology of DC-DC converter consisting in two serial connected half-bridges. Secondary circuit is realized like a conventional full-wave rectifier. The main advantage of this topology is the possibility of dividing the input voltage between the half-bridges. https://www.bekindtopets.com/flash-pick-Ovation-Toddler-Metallic-Schooler-Helmet-XXSmall-XSmall-hot-choice/
