Abstract (en)

[origin: WO2014044551A1] In order to drive a load (2), particularly to drive signal lamps in a signal system for rail vehicles, by means of a clocked voltage converter with two converter modules (M1, M2) on the input side connected in parallel, preferably functioning as buck converters, said modules are driven by means of pulse-modulated (PWM and/or PPM) signals (S1, S2) in such a manner that the load (2) connected on the output side between the converter modules (M1, M2) is supplied with two voltage half-waves (Vo1(t), Vo2(t)) offset relative to one another by half a period, forming an alternating voltage.
