The RMS voltage in the AC circuit decreases due to the generation and offset in phase of the surge current of a rectangular shape relative to the voltage in the network, and a voltage waveform in an electrical AC network distorts. New energy characteristics are used to identify and eliminate the cause of the unsatisfactory performance of electric energy recuperators. These characteristics are based on a revised law of conservation of energy in the electromagnetic field, mathematical modeling and the spectral analysis of non-sinusoidal voltage, current at the output of electric energy recuperators. In the process of the research, a decrease in the voltage at the output of the electric energy recuperators was taken into account during the switching of current in power semiconductor devices of the inverter and reduction in the duration of energy transfer to the AC network. The analysis of results of calculation of the energy process during the operation of the grid-controlled inverters showed that the phase shift of non-sinusoidal leveling current at the output of the inverter with relation to alternating voltage in network is followed by significant increase in its reactive component. To increase the voltage in the AC network, it was proposed to eliminate the possibility of inverter triggering using IGBT transistors, keeping the current advance phase angle at the output of the inverter relative to the AC network voltage to a minimum. The work provides examples of regulating the reactive power of the recuperator. In these examples, the RMS voltage of the overhead AC network increases due to the smooth change in current in the excitation windings of traction motors and switching of the traction transformer in the electric rolling stock.
