摘要： A resonant high current density transformer including two cores that are abut against each other with their first and second side posts on two sides thereof. A first bobbin envelops the first side posts on the same side of the two cores. A side plate is provided on either end of the first bobbin. The space between the two side plates is divided into two coil slots with a spacer, and at least a wire is wound in each coil slot to form a primary winding. A further second bobbin envelops the second side posts on the same side of the two cores. The outer periphery of the second bobbin is divided into two winding regions by another spacer, and a metal plate envelops each of the winding regions to form a secondary winding. A bobbin mount is disposed at the external flank of the second bobbin with a barrier plate at a side thereof for separating the first and the second bobbins. An insulating separating cover is provided on a side of the first bobbin closer to the bobbin mount, and the two ends of the separating cover cover the top and bottom sides of the first bobbin, respectively.

摘要： The invention relates to a lamp base (2) for a high-pressure discharge lamp comprising an ignition transformer (1000), which is placed in the interior (214) of the lamp base (2) and which serves to ignite the gas discharge inside the high-pressure discharge lamp. To this end, the ignition transformer (1000) comprises a core on which its windings (1001, 1002) are placed. The invention is characterized in that the core is formed by a first (1004) and by at least one second core part (1005, 1006, 1007), which are each made of a ferromagnetic or ferrimagnetic material and are separated by at least one gap (1008). The first core part (1004) has a cylindrical section on which the windings (1001, 1002) of the ignition transformer (1000) are placed, and core parts (1004, 1005, 1006, 1007) are formed in such a manner that the core, apart from the at least one gap (1008), has a closed shape.

摘要： The invention provides a current balancing circuit for powering a first load with a negative dynamic resistance and a second load with an essentially different negative dynamic resistance, and a transformer with such turns ratio that at least at an operating frequency impedances of the first and second windings complement the resistances of the first and the second loads, respectively, to a common value.
