Abstract

A filter circuit is provided in the secondary of a power transformer following a rectifier and is composed of two chokes respectively arranged in the series arms of the lines leading to two output terminals, and at least one shunt capacitor. Each of the chokes is composed of a winding fashioned as a strip-shaped interconnect, whereby both windings are conducted through a common magnetic core in the same winding sense.
