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.
