Three-phase phase-modular isolated power factor correction rectifiers are an interesting alternative to phase-integrated three-phase rectifiers as matrix-type phase modules allow a single-stage isolated energy conversion between the three-phase mains

Semiconductor switches possess nonideal behavior which, in case of isolated dc-dc converters, can generate dc-voltage components which are then applied to the isolation transformer. This dc-voltage component is translated into a dc flux density compo

Phase-modular isolated PFC rectifiers are an interesting alternative to phase-integrated three-phase rectifiers. The use of a matrix-type converter allows to achieve isolation with a single-stage energy conversion. This paper presents a phase-modular

In the public low voltage mains the stress caused by harmonic currents is strongly increased due to the higher demand of electronic equipment in everyday use. Therefore, standards were created in order to limit the harmonic currents injected into the

In grinding applications the processing of hard ceramics can be improved, if an ultrasonic axial vibration is superimposed to the rotation of the grinding tool in the grinding spindle head. The ultrasonic vibration is generated with a piezoelectric t

In many applications electrical energy has to be transferred to rotating parts. Usually a cylindrical transformer with a rotating and a stationary part is used, which are separated by a small air gap. In order to achieve a high magnetic coupling, on

The non-ideal behavior of semiconductor devices used in power electronic circuits exciting a transformer can cause DC voltage components applied to the transformer terminals. This DC voltage in turn generates a DC current and/or DC flux density compo
