摘要： A power supply apparatus which includes a transformer having a primary winding and a secondary winding, whereby magnetic flux generated by a varying primary voltage applied to the primary winding induces a varying secondary voltage on the secondary winding, a torroidal transformer core over which said primary winding and secondary winding are applied, and at least one magnetic shunt arranged to provide a diversion path for magnetic flux generated by the primary winding which diverts magnetic flux from the secondary winding.

摘要： A current transformer supplying a power for an electronic controller comprises two independent core magnetic circuits, wherein a first core magnetic circuit is a closed loop formed by connecting a U-shaped core and a linear core, a primary conductor extends through the closed loop, and a secondary winding for power supply is wound on the linear core; a second core magnetic circuit having an opening shape is disposed in parallel to the linear core of the first core magnetic circuit, and the open end of the second core magnetic circuit is coupled to the first core magnetic circuit through air gaps. The area of the cross section of the linear core is less than that of the cross section of the U-shaped core, so that the linear core can be magnetically saturated earlier than the U-shaped core. The centerline length of the U-shaped core is 1.5 to 4 times of that of the linear core. The current transformer of the present invention can not only normally start and work in case that a primary current is far lower than a rated current In, but also achieve the purpose of inhibiting rapid increase of an output current of the secondary windings and smoothing the output current in case that the primary current is far more than the rated current In.

摘要： A radio frequency (RF) signal combiner/splitter (40) may include a printed circuit board (PCB) (41) having first and second opposing major surfaces (49, 51), and openings (55a-55c) therethrough. The RF signal combiner/splitter (40) may further include a ferromagnetic body (45). The ferromagnetic body (45) may include a first portion (47) spaced from the first major surface (49) of the PCB, a second portion (48) spaced from the second major surface (51) of the PCB, and interconnecting portions (46a-46e) coupling the first and second portions (47, 48) and extending through respective openings in the PCB. The PCB may include conductive traces (42, 43) cooperating with the ferromagnetic body (45) to define circuitry for combining/splitting RF signals. For example, the PCB may further comprise additional conductive traces cooperating with the ferromagnetic body to define impedance matching circuitry coupled to the circuitry for combining/splitting RF signals.

摘要： The present invention discloses a high frequency transformer and a multi-output constant current source with the high frequency transformer. The high frequency transformer comprises a magnetic core (C), a primary winding (Np) and a plurality of secondary windings (Nsl, Ns2), wherein the plurality of secondary windings and the primary winding (Np) are arranged separately, and each secondary winding constitutes a parasite current transformer with the primary winding (Np). The parasite current transformer ensures that the magnitudes of the currents flowing through the plurality of secondary windings (Nsl, Ns2) maintain a required proportion between each other.
