Abstract

The invention relates to electrical engineering. The technical result of the invention is increased energy efficiency. The present device comprises three modules connected in parallel for generating pulses which impinge on the plates of a piezo actuator. Each module is connected to a direct current power source having a storage capacitor connected thereto, and is formed by two half-bridges, the midpoints of which are connected by a storage choke, and a device for controlling electronic switches. In a first embodiment, the modules are identical. The first and second half-bridges consist of switches connected in series, to which diodes are connected in parallel. In a second embodiment, the middle module of the above-described device additionally contains a third half-bridge connected in parallel to the first half-bridge and formed by a diode and a switch connected in series. A choke is connected in between the midpoints of the third half-bridge and the second half-bridge. In a third embodiment, all three modules are identical. The first half-bridge of each module consists of two switches connected in series, to which diodes are connected in parallel, and the second half-bridge is formed by a diode and a switch connected in series. In a fourth embodiment, a third half-bridge is additionally connected in parallel to the first half-bridge of the second module, said third half-bridge being formed by a diode and a switch connected in series. The midpoints of the third half-bridge and the second half-bridge are connected by a choke.
