Obtaining a constant voltage from a high-voltage piezo generator

The relevance of the problem of obtaining a constant voltage from an educational piezoelectric generator is substantiated. It is shown that the solution to the problem is to connect a two-half-period rectifier to the piezoelectric generator, assembled according to a bridge circuit and loaded onto a high-voltage capacitor. The key points of the didactic research carried out by undergraduate teachers and students during the period of educational technological practice are described in detail.
