Abstract

A converter mounting comprises a memory coil inductance (8), a memory primary capacitor (3) mounted upstream of said coil inductance, and a memory secondary capacitor (4), in particular, a piezoelectric actuator, mounted downstream of said coil inductance. Through control of a primary circuit element (12) and of a secondary circuit element (14), the energy of the memory primary capacitor (3) can be transferred to the memory secondary capacitor (4) and recovered.
