Abstract :
A linear and direct method of determining the frequency dependent impedance of a 12 pulse HVDC power converter is presented. Terms are developed for both the DC and AC side impedances of the power converter, including the effect of the firing angle control system, the commutation period, and the variability of the commutation period. The impedance predictions are verified by dynamic simulation
