Piezoelectric transformer parameters evaluation

2010 IEEE 26-th Convention of Electrical and Electronics Engineers in Israel, 2010
Power electronic circuits have traditionally been based on magnetic technology. The transformers and inductors in conventional converters are usually bulky compared to other elements. In an effort to miniaturize power components a piezoelectric, rather than a magnetic transformer could be employed in the power supplies.

One-parameter symmetry transformations

Il Nuovo Cimento A Series 10, 1967
A theorem is proved for one-parameter groups of automorphisms commuting with the time trnnslations. Si dimostra un teorema per i gruppi ad un parametro degli automorfismi che commutano con le translazioni del tempo.

Affine Parameter Estimation from the Trace Transform

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2003
In this paper, we assume that we are given the images of two segmented objects, one of which may be an affinely distorted version of the other, and wish to recover the values of the parameters of the affine transformation between the two images. The images may also differ by the overall level of illumination.

Parameter extraction of ferrite transformers using S-parameters

Proceedings of 14th International Power Electronics and Motion Control Conference EPE-PEMC 2010, 2010
A characterization of ferrite transformers based on S-parameters measurement using vector network analyzer and specially developed PCB test fixture is presented. Ferrite transformers are realized with commercially available ferrite component. In addition, in order to verify the measurement procedure, we have tested the same component using impedance ...
