Abstract :
The relationship between grounding systems and a high-voltage direct current (HVDC, 380-V DC) power supply system is presented. To assess the effect of grounding system configurations, a simple model of the HVDC power supply system was assumed, and two typical grounding models were evaluated. The noise emission level (conductive disturbance) was measured by using a prototype HVDC rectifier. By use of the measurement results and evaluations, the advantages and disadvantages of these grounding systems are discussed.
