Abstract
Abstract A transfer coil consisting of a loop provided with a sufficient electrical insulation is fed by an AC source and is inductively coupled with a plurality of cells. Each cell consists of a winding coupled with the loop and a rectifier circuit fed by the winding. The outputs of all rectifiers are in series aiding relation. In a first embodiment the loop is closed and inductively coupled to the source, making it possible to connect it to half the high voltage. In another embodiment, the loop ends are connected to a winding inductively coupled with the source and the loop is at the source DC potential.
