<p>The invention relates to a circuit (1) for highly efficient driving of piezoelectric loads (2), comprising a linear driving circuit portion (3) connected to the load (2) through an inductive-resistive connection whereto a voltage waveform is applied. Advantageously, the circuit comprises further respective circuit portions (4, 5), structurally independent, connected in turn to the inductive-resistive connection through respective inductors (L1, L2) to supply a considerable fraction of the overall current required by the load (2) in the transient and steady state respectively.</p> |
