The Influence of the Transformer Core Material on the Characteristics of a Full-Bridge DC-DC Converter

The paper analyzes the influence of material from which ferromagnetic core a transformer is made on characteristics full-bridge converter. Experimental investigations were carried out for three bridge converters containing transformers with ring cores various materials: iron powder, ferrite, and nanocrystalline material. properties aforementioned considered in wide range changes input voltage, load resistance, as well frequency duty cycle control signal. Based obtained measurements results relationship between parameters used values output energy efficiency full converter was discussed. method modeling SPICE program analysis this proposed. correctness model demonstrated powdered core.
