An integrated electromagnet comprises a magnetic yoke and magnetic poles in two rows. An axis of magnetic core in the magnetic pole is perpendicular to the magnetic yoke. The magnetic poles comprise first and second magnetic poles that are arranged alternatively in a row. The first magnetic pole in any row is adjacent to the second magnetic pole in the other row. The first magnetic poles in a row are connected to a one-way output controller and the second magnetic poles in a row are connected to a bidirectional output controller. In a guiding state, the magnetic poles in a row have a same polarity, and a polarity of the magnetic poles in one row is opposite to that in the other row; current output by the bidirectional output controller in a braking state has direction opposite to current output by the bidirectional output controller in the guiding state.

An electronic module comprising electrical components on a circuit board and a molding body disposed on the circuit board to encapsulate the electrical components, wherein a recess is formed in the molding body for exposing an electrode of the electronic module for connecting with an external component.

The present invention relates high power AC steering flux cancelling inductors and processes of making and using same. When properly configured and wired such inductors, separate the AC component and DC component of a high power current thus allowing the smaller AC fraction of the overall current to be carried by much smaller cross-sectional litz wires. Such high power AC steering flux cancelling inductors are more efficient at avoiding core saturation compared to standard inductors, yet they are less expensive without the need for large cross-sectional litz AC carrying wires. In addition to the aforementioned benefits, such high power AC steering flux cancelling inductor permits the levels of AC and DC current to be efficiently monitored as such currents are separated.

An inductor that is configured to store energy in a magnetic field includes a wire and a core. The wire is configured to deliver electrical current to the inductor to generate the magnetic field. The core is disposed radially about the wire. The core comprises magnetic particles that are suspended in a non-magnetic matrix. The magnetic particles are arranged such that a magnetic permeability of the core increases in a direction that extends radially outward from the wire along a cross-sectional area of the magnetic core from a first region that is adjacent to the wire to a second region that is adjacent to an outer periphery of the magnetic core.

A magnetic element is provided and includes a first magnetic core, a second magnetic core and two windings. The first magnetic core is made of a first material and includes two winding pillars and two connecting parts. The first magnetic core has a first permeability. The second magnetic core is made of a second material and has a second permeability. The first permeability is less than the second permeability.
