Abstract :
The paper deals with the problems of Electromagnetic Compatibility (EMC) of the frequency control drive of the electromotive switch actuator of the railway switch. The frequency converter with Pulse Width Modulation (PWM) and the output sinus filter are used for feeding of the asynchronous motor of the switch actuator. This drive is operated in the isolated system of feeding voltages. The drive is fed by the frequency converter with unshielded cable with length up to 1.2 km. The EMC problems occurring at development and operating of drive are analyzed in this paper. This paper completes and specifies [1].
