Research on PWM control strategies of active power filter with series resonance designed for mine hoists
WANG Xue-dan
Abstract：Aimed at attenuating the harmonics caused by high power DC drive system,proposed a new PWM topology of converters, that is, work styles of the hybrid energy storage in DC side and series resonant to form the new type of parallel active filters with reactive and active. Introduced the PWM control strategy of the new active filter with reactive and active and a harmonic control strategy based on the Fourier transform to compensate for harmonic of the 5th ,7th, 11th, 13th in three-phase power system. The proposed control strategy was accomplished through TMS320F240 DSP. In the laboratory, experimental prototypes were constructed to carry out experimental study. The present study finds that the harmonic of the 5th,7th, 11th, 13th in the system is subjected to better suppression, so that the THD of net-side currents decreases from 26. 4% to 12. 8%, with a significant reduction in total harmonic distortion rate, which verifies the effectiveness of the control strategy and its implementation.
