Design on Electromagnetic Compatibility of Electrical Driving System Controller Based on Computer Control

Abstract:

This article analyses the electromagnetic interfering sources and its transmitting ways inside electric driving system controller and expounds the anti-disturbing methods in designing the electromagnetic compatibility of electric driving system controller. Among that the interfering sources are the rectifiers and inverse transformer in the AC frequency converter and the interference signals from electric network, the transmitting ways of the electromagnetic interfering signals include transmitting in electric wires, radiating and coupling through space, and the anti-disturbing methods have (a) separating interference sources with the system or devices, (b) connecting filters in the output ends of interfering sources and the input ends of the devices easily to be interfered, (c) shielding the interfering sources, (d) grounding correctly and reliably, (e) adding circuit power filters. The experimental results demonstrated that the anti-disturbing methods mentioned above are very effective for the electric driving system controller based on computer control.
