Abstract: A capacitive reactance voltage transformer includes a magnetic core and a coil unit. The coil unit includes stacked coil modules. The magnetic core has a leg portion through which a closed magnetic loop path passes, and on which the coil modules are sleeved. Each of the coil modules includes first and second windings, and an insulating baseboard through which the leg portion of the magnetic core extends. The first and second windings are disposed on the insulating baseboard and are spaced apart from each other. The first winding surrounds the leg portion of the magnetic core in such a way as to substantially correspond to the second winding. The first windings are connected in parallel, and the second windings are connected in series.

Abstract: A signal transmission system includes a switch component and a choke component each coupled to one of a first power wire and a second power wire, a first conductive path between the switch component and a load, a second conductive path between the choke component and the load, and a control block. The control block controls the switch component to not conduct when providing a control signal to the first and/or second conductive paths. When the switch component does not conduct, a magnetic core of the choke component does not reach magnetic saturation. When the switch component conducts, the magnetic core of the choke component operates at magnetic saturation.
