In this work, after analysing the nature of the power harmonics generated by an A.C. excited generator, an in phase correlation filtering technique based on the frequency shifting principle was adopted; the topologic structure of the filter and the detection control method for suppressing harmonics were investigated and a more idealized hybrid filter and its composite detection control were developed. The low frequency harmonic compensation signal's difficulty in passing through the injection transformer of a series APF was effectively solved by using pulse width modulation (PWM) technique and magnetomotive force (MMF) compensation principle. Simulation and experiments proved this measure is good in filtering performance, stable in system operation and, especially, self adaptive to the varying fundamental frequency. As a result, compared to the conventional methods,this is a more effective harmonic suppression scheme suitable for complex power supply system such as the A.C. excited generator.
