Abstract

A conversion apparatus having transistors, comprising means for inverting a DC voltage in order to obtain an AC voltage, means for filtering the AC voltage, including at least one parallel inductor L.sub.p, the device being capable of operating above a resonant frequency F.sub.p. The conversion apparatus comprises means for predicting a zero crossing of the instantaneous current I.sub.1p in the parallel inductor L.sub.p, and means for causing a transistor of the device to switch if a zero crossing of the current I.sub.1p is predicted.
