  abstract = {Piezoelectric transformers are well known since the publication of
	some patent applications at the end of the 1950s. But until today
	their only business use lies in the field of backlighting systems
	for LCDs. Due to key features as light-weight, flatness, high step-up
	at low volume and high efficiency piezoelectric transformers should
	be usable in a much broader range of applications. This contribution
	returns to mind their operating principle, shows how to model and
	to develop such devices as well as give some aspects for development
	trends that will lead to further applications.},
