A power converter device for a switched reluctance motor, comprises a semiconductor circuit arrangement in the form of an asymmetric inverter (T1, D1; T2, D2), to supply one of the motor windings (4, 6) on the reluctance motor with current or to commutate the current from the winding. According to the invention, the achievement of the maximum possible current amplitude may be accelerated and the commutating of the current from the motor winding (4, 6) may be accelerated, whereby, in addition to the main voltage source (Ud), an additional voltage source in the form of a circuit extension (SE) is provided, which, by means of providing an additional voltage of corresponding polarity, accelerates the current feed to the relevant motor winding (4, 6), or accelerates the removal of the current (commutating) from the motor winding.
