Abstract
The utility model discloses a converter suitable for series topologies formed by integrating a plurality of magnetic components, which comprises a direct-current power source and a converter circuit with the series topologies with the plurality of magnetic components. The converter circuit powered by the direct-current power source comprises an integrated magnetic component, and coils are wound on the integrated magnetic component and form a transformer and inductors. The converter with the integrated magnetic component integrates inductors and a transformer in an original circuit, and accordingly the integral volume of the converter is decreased. The integrated magnetic component is provided with a plurality of pairs of columnar magnetic cores, and required value of resonant inductors can be reached by reasonably adjusting the number of turns wound on the columnar magnetic cores and air gaps among the columnar magnetic cores. Owing to decrease of the volume, power density of the converter is improved correspondingly, and simultaneously emergencies such as leakage inductance and the like are controlled conveniently.
