Abstract: A power adapter hub is provided, comprising: an AC input port; a power supply circuit coupled to the AC input port for receiving AC power and having a maximum rated output power; and a plurality of output ports coupled to the power supply circuit for supplying DC power to external devices. Upon determining that the total power to be supplied might exceed the maximum rated output power, a DC power supplied through at least one of the output ports is modified, and the modified DC powers are set to ensure that the supplied power does not exceed the maximum rated output power.

Abstract: Embodiments of the present invention comprise systems and methods for providing power from DC output ports, typically smart ports, to electronic devices, not necessarily having smart input DC ports. A power adapter cable is provided comprising a control unit that adapts between a smart output port and a DC input port that may not be compatible with the smart output port. Also provided embodiments of a power adapter hub wherein the power supplied through its output ports is selectively reduced in the case of overload, according to a predefined policy.

Abstract: A magnetic induction device (MID) is disclosed. The MID includes a core, and at least one first winding including at least one conductive strip deposited on the core and including at least two turns which are substantially simultaneously shaped. Related apparatus and methods are also disclosed.

Abstract: A magnetic induction device (MID) is described. The MID comprises at least one primary electrical winding, at least one secondary electrical winding, and an electrically-conductive cover (BCC) which is electrically connected to a local ground and at least partially surrounds, without forming a closed conductive loop, a core via which the at least one primary electrical winding and the at least one secondary electrical winding are magnetically coupled. Related apparatus and methods are also described.

Abstract: Apparatus for reducing a common mode (CM) electromagnetic interference (EMI) in a balanced transmission line which carries a differential signal occupying a specified frequency band is described. The apparatus includes a first Single Ended Filter (SEF) operatively associated with a first path of the balanced transmission line, and a second SEF operatively associated with a second path of the balanced transmission line, wherein a ground terminal of the first SEF and a ground terminal of the second SEF are electrically connected to a local ground. Related apparatus and methods are also described.
