Professional Educational Seminars

Although piezoelectricity was discovered about 100 years ago, piezoelectric elements (PE) became only recently a practical alternative in some power conversion applications. In a number of applications, the piezoelectric approach was shown to have a clear advantage over alternative solutions. In other applications, piezoelectric elements will clearly be a preferred choice if and when their price is lowered. Notwithstanding the relative simple structure of piezoelectric elements, the design of the power electronics circuitry associated with them is far from being simple or trivial.
The objective of this seminar is to cover PE technology from the power electronics point of view. This will be accomplished by first introducing the models of native PE devices and when loaded by rectifiers and mechanical loads. This knowledge will then be used in the presentation of the theory of drivers and rectifiers. Finally, the seminar will address some specific open problems that haunt researchers and designers such as the issue of instability that may develop when a PE drives fluorescent lamps.
