Kaluigniy S. Electromechanical systems of the concerted rotation with the power of the current-parametric valve transformer

The electromechanical energy conversion processes in an interconnected electric drive concerted rotation of AC and DC. Improving performance and energy indicators related electromechanical systems concerted rotation (EMSCR) of AC and DC power through the use of new properties of the drive when powered engines from current sources. General methods of mathematical analysis, the matrix and the operational calculus methods, the theory of electromechanical energy conversion, mathematical and physical modeling. The development of new promising structures interconnected EMSCR of AC and DC-based of current-parametric converter; investigated energy regimes and electromagnetic processes in automated EMSCR, design procedure and to select items converters supplying EMSCR of AC and DC. Theoretically substantiated and experimentally confirmed that a EMSCR should be used from the current source: the armature DC motors interconnected drivers are encouraged to implement a current-parametric valve transformer (CPTV) and the transformer of current-parametric asynchronous valve cascade (CPAVK) and obtain characteristics that allow a qualitative and quantitative evaluation of the current and voltage on the elements of electric power circuit, the equations of mechanical characteristics of interconnected drivers DC-based power sources and improved method of pie charts to calculate the mechanical properties of electric with using the transformer of CPAVK proved that in the scheme of motor with using the transformer of CPAVK is able to work as a machine dual power, with "torque" section of mechanical characteristics can be used to match the rotation of several motors, analytically shown a significant increase in the frequency properties of the channel disturbances related to the proposed electric power system, which reduces the elastic moments that integrate the motor shafts.
