Abstract :
A novel power factor control scheme for high power GTO current source converters is proposed in this paper. Using both feedforward and feedback control techniques, the proposed scheme guarantees that the input power factor of the converter can be kept at unity or a maximum achievable value. Another feature of this scheme is parameter insensitive, that is, variations in the line and load impedance or changes in the filter capacitor size will not affect the process of tracking the maximum input power factor. No parameters in the control scheme should be adjusted to accommodate such variations or changes. Simulation results are provided to verify the operating principle of the scheme
