Piezoelectric transformer, has base plate whose upper surface is provided with insulation separation layer arranged between input and output units, and thermally shrinkable cover is provided on separation layer

摘要

The transformer has a base plate on whose upper surface is provided with an insulation separation layer. A thermally shrinkable cover (22) is provided on the separation layer, and a coupling layer provided between the cover and the base plate along with the cover forms an insulating interlaminar bonding. The separation layer is arranged between input and output units of the transformer, where the input unit includes internal electrodes.
