Abstract:Aiming at the problem of two-stage matrix converter (TSMC), which input power factor varies with system parameters and loads conditions, a input current feedback control strategy with phase compensation component for TSMC is proposed, which ensures input currents following input voltages without steady-state error. The theoretical basis of this strategy is given based on deducing TSMC model and analyzing input power factor angle characteristic. Finally an experimental prototype based on DSP+CPLD is built. The experimental results indicate that TSMC not only owns the excellent driving-performance, but also can always achieve unity displacement factor regardless of system parameters and load effect. Moreover, the total harmonic distortion (THD) of input currents is reduced and the system input currents become more sinusoidal. Thus, the feasibility and validity of the proposed strategy are verified.
