Piezoelectric transformer for integrated power supply of compact electrical module, has parts with electrodes aligned perpendicular to main surface and connected with each other, and contact surfaces arranged on main surface

摘要

The transformer has a body (1) with two mechanically functional parts (2, 3) connected with each other. Two sets of inner electrodes (4-7) of the functional parts are aligned perpendicular to a main surface of the body. The inner electrodes are conductively connected with each other, and two sets of contact surfaces (12-15) are arranged on the main surface. The inner electrodes are attached to collector electrodes (8-11), where the collector electrodes are conductively connected with the contact surfaces. The collector electrodes are arranged on a side surface of the body.
