In proximity welding, two metal pieces are placed in proximity and high-frequency current
When a unipolar unit is used in the cutting mode, the high-frequency current
passes through the target tissue, and the active electrode functions as a bloodless knife by disintegrating the cells at the edges of the wound.
Surgical procedures can be performed by focused heating of the tissue, by using electronic devices based on the high-frequency currents
, laserbeams, argon(gas) and microwaves.
An arc causes momentary high-frequency current
spikes that ride on the low-frequency current waveform.
take the path of least inductance or the path of least loop area.
Tesla explained his decision to start researching high-frequency currents
, previously completely unknown: "Some theoretical possibilities offered by currents of very high frequency and observations which I causally made while pursuing experiments with alternating currents, as well as the stimulating influence of the work of Hertz, determined me some time during 1889 to enter a systematic investigation of high frequency phenomena.
However, this can cause higher losses due to the high-frequency currents
in conductors and the load caused by the skin effect and higher eddy-currents.
Because the transformer is a large inductive element subjected to high-frequency currents
, it is typically the noisiest component.
The course will cover circuit parasitics, high-frequency currents
, signal and wave propagation, propagation time and velocity, PCB properties, transmission line impedance, impedance models, trace routing and termination, and the effects of vias and trace corners.
The experiments showed that the problems were caused by asymmetric distribution of high-frequency currents
in the motor," Haring said.
