Original Kurzfassung:
In this paper the concept of a hydraulic buck converter driving a load at resonance is discussed. The
performance is compared with conventional proportional control and proportional control of a resonant
drive. As an example the oscillation drive for a mould of a continuous steel slab caster is taken to benchmark
the concept. Such moulds have typically a weight of 20 tons and are oscillated at frequencies up to 5 Hz and
a stroke of 7 mm. It is shown that a good performance and substantial energy savings compared to
conventional hydraulic resistance control can be achieved with this concept.
