提出了一种新型的大功率GTO电流型变流器功率因数控制方案。同时使用前馈和反馈控制技术，所提出的方案保证变换器的输入功率因数可以保持在单位或最大可实现值。该方案的另一个特点是对参数不敏感，即线路和负载阻抗的变化或滤波电容器尺寸的变化不会影响跟踪最大输入功率因数的过程。控制方案中的任何参数都不应调整以适应这种变化或变化。仿真结果验证了该方案的工作原理。
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.
