摘要： The invention relates to electrical engineering, technology for producing high voltages, portable devices for supplying a high voltage to ozonizers, ionizers, gas-discharge lamps and lasers, technology for producing nanosecond pulses, and primarily to output stage technology for electroshock devices. The technical result is reduced weight and dimensions, an improved manufacturing process and a reduced price. A high-voltage pulse transformer preferably comprises a secondary winding wound on a preferably removable support element, without a mandrel, frame, template or sleeve, in layers with insulation between said layers, and a primary winding separated from the secondary winding by insulation between the windings. The entire structure is potted with an electrical insulating compound or an electrical insulating liquid.

摘要： A reactor includes a coil, a magnetic core, and a holding member holding an end face of the wound part in an axial direction and an outer core part of the magnetic core. The holding member is a frame-shaped body having a through hole into which an end portion of the inner core part is inserted. The outer core part has an inward surface opposing the inner core part, an outward surface on an opposite side to the inward surface, and a plurality of peripheral surfaces joining between the inward surface and the outward surface. The reactor includes a core coupling member, coupling the outer core part and the inner core part, having a supporting piece supporting the outward surface of the outer core part, and an engaging leg piece having a distal end engaging a peripheral surface engaging part formed on a peripheral surface of the inner core part.

摘要： A method of assembling a quasi-planar transformer can include passing a continuous wire through an opening in a printed circuit board having one or more printed circuit traces that define one or more printed circuit windings of the quasi-planar transformer, winding the continuous wire in a first direction to form a first half of a wire-wound winding on a first side of the printed circuit board, and winding the continuous wire in a second direction opposite the first to form a second half of the wire-wound winding on a second side of the printed circuit board. The method can further include securing the first and second halves of the winding to the printed circuit board. The continuous magnet wire can be self-bonding wire and securing the first and second halves of the winding can include applying heat to the assembly.
