Abstract

A converter unit includes: a housing with a moulded-on hollow cylinder that extends into the housing; a non-magnetic toroidal core supporting a first secondary winding, contacting the housing bottom concentrically with the hollow cylinder and is embedded in a solid compound; a magnetic toroidal core supporting a second secondary winding, arranged concentrically with the hollow cylinder above the non-magnetic toroidal coil; and a casting compound with which the housing opening is closed. To achieve a compact converter unit, a first planar spacing element is arranged between the first and the second secondary windings, directly contacting the first secondary winding and the second secondary winding. In addition, electrically insulating particles fill out the space between the second secondary winding and the housing wall, and the casting compound extends at least up to the particles, which lie at the top towards the housing opening.
