Integrated Magnetic reactor

The invention discloses a magnetic integrated reactor. Each phase of the reactor comprises two reactor units serially connected, wherein cores in the reactor units share at least one yoke. Core stems of the reactor units are coaxially arranged into an upper reactor unit and a lower reactor unit. The core of the upper reactor unit comprises an upper yoke, an upper core stem and a lower yoke. The core of the lower reactor unit comprises an upper yoke, a lower core stem and a lower yoke. The lower yoke of the core of the upper reactor unit and the upper yoke of the core of the lower reactor unit are shared, so that an intermediate yoke is formed. The upper yoke and the upper core stem in the core of the upper reactor unit and the intermediate yoke form another closed magnetic circuit. Compared with two separated reactors, the magnetic integrated reactor has one yoke omitted, so that the size is reduced and the cost is reduced. In addition, core loss is reduced accordingly.
