Abstract

The device has a clocked converter (2') with a transformer for electrical isolation of the mains side and the low voltage side and an earthed housing. The coupling capacitance (Ck1) between transformer windings is reduced by a special winding layer structure and a converter switching method is selected with low transformer current gradients, in particular a resonance blocking converter is used with a clocking frequency greater than 25 kHz.
