The development stage readiness: Ready for application

Technical and economic effect: Due to synchronized nesinfaznomu management currents of individual modules are displaced in time, which provides improved power parameters as input and output of the current regulator. Simultaneous use of synchronous nesinfaznogo control and high energy conversion drastically reduces the parameters of the output filters, to realize high performance mining regulator and control signals to achieve optimal transient under perturbations in the load.

Description of the development:
()
In the current controller PT-200 power conversion occurs at a frequency of 20 kHz. In order to construct controllers using a modular principle, the basis of the power modules are IGBT transistors. Application of a modular principle allowed to evenly distribute electrical and thermal loads between the structure nodes, thereby reducing the energy density of the heat and to simplify the design of the controller. Controlling the amount of output current and the control parameters of electric power at the outlet and inlet of the RT-200 is carried out both in local control, and remotely.
