English term (edited):
voltage slope = rate of change of voltage
rythme de variation de tension
Please note that the EN term is being used incorrectly here; the definition of it as dv/dt (the differential of the voltage with time) makes it clear that we are not dealing with a slow change in voltage over a period of time (= voltage slope, e.g. for a discharging battery), but rather, with the instantaneous rate-of-change of this voltage. This is shown both by the use of the mathematical expression dv/dt, and also, the figure given of 500 V / µs (instead of, say, volts per hour etc.)
I have found plenty of examples of the expression 'rythme de variation de...' out there on the 'Net, and the collocation with dv/dt in certain examples is clear evidence.

In a typical configuration, the output filter (low-pass) is here being used to reduce the rise-time of the waveform (typically required to avoid radiating interference due to fast rise-time wavefronts)

i'll bet this is all about filtering the chopper output voltage? These things are notoriously 'dirty' and can produce horrendous interference if it isn't filtered out at source.
In the early days of designing the Eurostar, they had a nightmare, as the locos had to work on both the European overhead catenary system (high voltage / low current) AND the British 3rd-rail system (low voltage / high current); when the FR trains came onto the GB rail system, the higher current produced bigger arcing problems, in turn generating horrendous problems due to interference with the control electronics.

Alain Boulé
: another term could be "front de tension". Filtrer revient à réduire les fronts de tension.

Merci, Alain ! Yes, although is that OK for a continuous waveform too, as distinct from a pulse or step change? Here, it looks very much as if we're talking about filtering chopper output sq./waves into something more like a sinewave...

Discussion
In particular, we wouldn't usually says 'cares for' in this sort of technical document; the (rather informal) term they are probably trying to use is 'takes care of'.
Likewise, I think the use of 'voltage slope' is arguably wrong; dV/dt would more usually be referred to as 'the rate of change of the voltage', and I believe needs to be translated accordingly.
