Abstract
This application provides a magnetic integrated device, a power conversion circuit, a charger, and an electric vehicle, and pertains to the field of power electronics technologies. The magnetic integrated device includes a magnetic core, a first transformer winding, and a second transformer winding, where the first transformer winding and the second transformer winding are separated and wound, and a first air gap is formed at separation. A magnetic line may pass through the first air gap to form leakage inductance, and the leakage inductance may be equivalent to resonant inductance in the power conversion circuit. Therefore, there is no need to separately dispose an inductor winding in the magnetic integrated device. This effectively reduces a volume and a weight of the magnetic integrated device. In addition, the power conversion circuit that uses the magnetic integrated device also has a relatively small volume and relatively high-power density.
