| 中文摘要 | 分析了四象限级联型多电平变换器的功率单元中,H桥逆变器输出功率的脉动对PWM整流器控制尤其是对其直流母线电压的影响。提出外环控制器为直流母线电压反馈与负载功率前馈相结合、内环电流控制为比例积分加谐振(PIR)调节器的PWM整流器控制策略。实验表明该控制策略即使在直流母线电容容量很小时,仍然能得到较为稳定的直流母线电压,验证了控制策略的有效性。; In power cells of the four-quadrant cascaded multilevel converters,the output power of H-bridge inverters is pulsating,which influences the control of the PWM rectifier,especially on the DC-link voltage. A novel control strategy for the PWM rectifier is proposed in this paper. The outer loop controller is made up of the DC-link feedback controller and the load power feedforward controller. The inner loop current controller is a proportional-integral-resonant (PIR) regulator. Experimental results show that the DC-link voltage is well-controlled even with a very small DC-link capacitor,which confirms the effectiveness of proposed control strategy. |
