Possibilities of efficiency improvement in relativistic electron devices with initially linear electron beams by providing resonance condition for Cerenkov and cyclotron interactions simultaneously are studied theoretically and by computer simulation. The main difference from previous research is investigation of dynamic cyclotron resonance. The dynamic cyclotron resonance occurs in strong nonlinear regimes when the electron beam is separated by electromagnetic field in groups of accelerated or decelerated particles. For strong nonlinear regimes of interaction one can select some groups of electrons that interact with the electromagnetic field under the same Cerenkov resonance condition but under different cyclotron resonance conditions. It was shown that efficiency can be improved from usual value for Cerenkov interaction (25%--28%) up to 50% by choosing appropriate value of focusing magnetic field.
