Abstract
The invention relates to a circuit for highly efficient driving of piezoelectric loads, comprising a linear driving circuit portion connected to the load through an inductive-resistive connection whereto a voltage waveform is applied. Advantageously, the circuit comprises further respective circuit portions, structurally independent, connected in turn to the inductive-resistive connection through respective inductors to supply a considerable fraction of the overall current required by the load in the transient and steady state respectively.
