The invention relates to an electronic control device for a piezoceramic bending transducer embodied as a trimorph (10), wherein a first voltage divider (17) is provided, which comprises two resistance branches (18, 19) and can be supplied by a first voltage source (U) and the first resistance branch (18) of which connects the first piezoceramic plate (11) of the trimorph (10) to the interlayer (13) thereof. Furthermore, a second voltage divider (24) is provided, which comprises two resistance branches (25, 19) and the first resistance branch (25) of which connects the second piezoceramic plate (12) of the trimorph (10) to the interlayer (13) thereof. In this case, the second resistance branch (19) of the first voltage divider (17) also forms the second resistance branch (19) of the second voltage divider (24). As a result of this, what is achieved by means of a voltage source is that a tensile stress is applied to one piezoceramic plate and a compressive stress is applied to the other piezoceramic plate, such that the bending movement is supported by both piezoceramic plates and, as a result, only lower voltages have to be applied.
