Abstract

The voltage source converter (VSC) provides constant/controllable DC bus voltage, regenerating capability, controllable power factor, and nearly sinusoidal input current. If an input LC filter is added, it prevents pollution of the utility by the current ripple due to the pulsewidth modulation (PWM) switching. A novel control strategy for actively damping high-frequency resonance (above 1.5 kHz) in the input LC filter is presented. No additional sensors are required for the standard VSC. Theoretical results of the analysis and simulation are experimentally verified.
