Abstract

The arrangement has a mains rectifier (3) with an intermediate circuit capacitor (5) in parallel with the d.c. output, a power unit with a static inverter (7) operated at a first frequency and a further second static inverter (10a,10b) per load (2a,2b), each with 2 power switches operated alternately with a second defined frequency. The loads are connected between the junctions of the power switches in the first and associated static inverters. Independent claims are also included for the following: an arrangement for outputting ultraviolet rays, especially for polymerizing ink in a printer, and a method of operating an inventive circuit arrangement.
