Abstract

The introduction of high-speed rolling stock, the growth of passenger and freight transportation are placing ever greater demands for power supply devices and electric energy quality in a contact network. The application of direct current at traction substation along with uncontrolled diode rectifier of a controlled buck converter allows adjusting the average value of rectified voltage in the contact system. In addition, using the buck converter in a closed structure allows compensating the unwanted harmonic components of the load voltage. 

The need for investigating the dynamic properties of the “rectifier buck converters - load” system is specified by the possibility of realizing the finite duration processes in the voltage regulation channel, allowing the load voltage harmonic compensation on the feedback circle. 

The buck converter, operating in the pulse width modulation mode, allows using it as a wideband active filter. 

All the above requires a mathematical description of dynamic processes in the described system for the task solution. The obtained system of equations allows describing the dynamic processes in rectifying installation with width-controlled BC.
