- Abstract
- It is shown experimentally that in high frequency (HF) circuits current oscillations are accompanied by extremely high over-voltage (OV). These oscillations arise due to turn on of a finite part of the inductance coil during the half of oscillation period t = T/2, and inductance operation in an autotransformer mode. It is shown that peculiarities of this mode depend on the propagation velocity of electron conduction current through the coil wire. The effect of preliminary bias on HF oscillations in the LC-circuit is considerer. Analysis of commonly used electrical circuit over-voltage protection facilities is carried out.
