MATHEMATICAL MODEL OF THE MARX GENERATOR WITH SURGE WAVE TAIL COMPENSATION
KOMUNALNA ENERGETIKA / POWER ENGINERING, 28
This Paper presents a mathematical model of the Marx generator with surge wave tail compensation. Due to small inductance of low-voltage transformers windings, the tail of the impulse voltage decreases in such a manner that the impulse voltage shape no longer meets the IEC standards. In this case it is necessary to modify the Marx connection with the Glaninger circuit, which increases the time to half value.

PLANNING OF LABORATORY TESLA TRANSFORMER
KOMUNALNA ENERGETIKA / POWER ENGINERING, 21
Paper presents a calculation of the Tesla transformer, which was built in Powerlab at the Faculty of Electrical Engineering and Computer Science at the University of Maribor. The mathematical model is defined using differential equations and is solved by finding the eigenvalues and the corresponding eigenvectors in Matlab. Inductances and ground capacitance of the HV winding are obtained from the magnetostatic and electrostatic energies, respectively, and calculated using FEMM 4.2. The calculation method described represents the basis for the construction of the Tesla transformer.
