Abstract :
The effect of power converter impedance is mostly ignored when performing harmonic analysis since it is complicated to calculate and a common assumption is that it has minimal effect. This paper compares the use of simplified techniques against a rigorous calculation of the converter impedance and demonstrates their effect on the frequency response of the system.
