【Abstract】 In this paper,the work of phase-controlled AC-AC frequency converter loop-current were discussed,and applied Fourier mathematical method to deduce the output voltage function expression under different control and modulating signal,analysis of the output voltage harmonic components of the AC-AC frequency converter,and the impact of the size of loop-current,summarizes the AC-AC frequency converter control strategy for the smallest loop-current and to solve the the high-power AC-AC frequency converter,circulation of loop-current-limiting reactor problem,summed up the basic method of circulation control,and the working performance of AC-AC frequency converter is highly promoted.更多还原
