Research of an Adjustable DC Electric Drive in the Generator Braking Mode

Abstract

The article is devoted to the study of an adjustable DC electric drive with a compensated electric motor of independent excitation of the 4PF series in the mode of controlled generator braking. The linearization of the model is performed, a linear transfer function is obtained via the control channel. The dependences of the oscillation index and the time constant in the duty cycle function of the pulse converter in the braking mode are determined, the operating range of the braking mode is determined. As a result of theoretical studies, the operating range of the change in the duty cycle of the pulse converter in the armature circuit of the electric motor has been determined. The dependences of the correction coefficients for the transfer function of the linear part of the electric drive replacement circuit in the controlled dynamic braking mode are obtained, which allow taking into account the nonlinearity of the pulse converter
