| Abstract: | The mathematical model of three-level rectifier is introduced.Besides,the voltage-oriented control including di-rect current control is used,a novel simplified space-vector pulse width modulation is applied to reduces calculation and to simplifies the neutral-point potential control strategy.A three-level rectifier platform based on DSP TMS320F2812 is built up for this research.The validity of the control strategies is demonstrated by the experimental results. |
