| Abstract: |
| The B-C-SVM（Bipolar Current Space Vector pulse width Modulation） algorithm applied in HFLMR（High Frequency Link Matrix Rectifier） is introduced and a two-step commutation strategy is proposed，which does not need the hardware detection circuits of output current direction，resulting in higher reliability and lower cost. The strategy of HFLMR closed-loop control based on d-q coordinates system is established to achieve the unity power factor control，high-quality input current and high-quality output current／voltage within wide load variation range. Simulative results show the correctness and effectiveness of the proposed strategy. |
