The results of analytical research and computer design of the anomalous, steady-state and transitional modes related to the resonance in the input filter of voltage added converter based on IGBT with the PWM are presented. The ways of resonance remov

The structure of traction substation 3,2 kV DC power source is considered. It is shown that the output filter choke of traction substation with voltage added converter may be excluded. A dynamic model of voltage added converter is developed, its feat

The structure of the contact network power supply on the basis of series connection of angle- and PWMcontrolled rectifiers is considered; it allows (alongside with the capacity factor increase almost up to unit) to realize a number of the additional

The confinement mechanism earlier proposed by author is applied to describe the (possible) ground state of toponium $\eta_t$. For this aim the nonperturbative consistent approach is elaborated in both relativistic and nonrelativistic cases. The study

On the basis of the confinement mechanism earlier proposed by author the electric formfactor of π 0 -meson is nonperturbatively calculated. The latter is then applied to describing electromagnetic decays π 0 → 2 γ and π 0 → e + e − γ which

The recently obtained solutions of the Dirac equation in the confining SU(3)-Yang-Mills field in Minkowski spacetime are applied to describe the energy spectrum of charmonium. The nonrelativistic limit is considered for the relativistic effects to be

We remark that the standard black hole topology admits twisted configurations of spinor field due to existence of the twisted spinor bundles and analyse them using the Schwarzschild black hole as an example. This is physically linked with the natural

We describe U(N)-monopoles (N > 1) on Kerr black holes by the parameters of the moduli space of holomorphic vector U(N)-bundles over two-sphere with the help of the Grothendieck splitting theorem. For N = 2,3 we obtain this description in an explicit

We describe U(N) monopoles (N>1) on Kerr black holes by the parameters of the moduli space of holomorphic vector U(N) bundles over S2 with the help of the Grothendieck splitting theorem. For N=2, 3 we estimate the corresponding monopole masses.
