Peculiarities of current through systems of antiferroelectric and ferroelectric capacitors

Abstract

Behaviour of current through systems of capacitors made of ferroelectrics, antiferroelectrics and nonferroelectrics connected in parallel or in series is considered. A simple graphical way to solve the problem is proposed. The form of hysteresis loops of the systems differs essentially from those of constituent capacitors. At some conditions the current through the systems contains very high harmonics with large amplitude. Such systems can be used as simple and cheap frequency transformers.
