This paper proposes a method to damp the harmonic resonance at the dc-link of a large capacity rectifier-inverter system such as in rapid-transit railways. A voltage-source PWM converter is connected in series to the dc capacitor of the rectifier, acting as a damping resistor to the dc capacitor current. No filters axe needed to extract harmonic components from the dc capacitor current. This system is thus highly stable and the required rating of the PWM converter is very small. The basic principle of the proposed method is confirmed using digital computer simulation.
