Abstract

The circuit has a mains voltage rectifier (GL), a capacitor (C2) parallel to the rectifier's d.c. output, a static converter (Q1,Q2), a series resonant load circuit (C6,L5), a smoothing capacitor (C3) and a harmonic filter (D1,C7). A first connection of at least one harmonic filter capacitor is connected to a resonant capacitor, an electrode of a filter diode and the rectifier output; its second connection is connected to the static converter output. The second electrode of the filter diode is connected to the smoothing capacitor.
