This paper describes a damping control method of power converters for suppression of resonance in DC power network. The resonance occurs when a resonant frequency of the DC distribution line coincides with the frequency of the harmonic or interharmonic components generated by the power converters. For detailed investigation, a combined system which consists of a pulse-width modulated (PWM) rectifier and a PWM inverter is treated as the simplest example. To suppress the resonance, a DC-side damping control method is proposed and its implementation and design method are discussed in detail. Then, the proposed damping control method is applied to the combined system of a PWM rectifier and a PWM inverter. Experimental results verify the validity and practicability of the proposed damping control method.
