摘要
提出了一种新型三相不带或带有很小直流连接电容的逆变器,介绍了仅通过改变相应的调制波来消除逆变器输出电压谐波的重构SPWM技术。该逆变器采用了调制波重构技术,很大程度上消除了输出电压的谐波,同时减小了直流输出滤波器的尺寸。最后通过仿真和实验比较了基于调制波重构技术的新型变换器和基于传统技术的变换器的性能,结果验证了理论分析的正确性。
A novel three-phase uncontrollable rectifier inverter without or with a quite small dc-link capacitor, accordingly,a novel reconstruction technology,Modulation Wave Reconstruction Sine Pulse Width Modulation （MWR- SPWM） which can greatly eliminate harmonics in inverter＇s output voltage are proposed.Because the MWR-SPWM technique is adopted, the sizes of the input AC filter and the output AC filter are reduced.The performance of this inverter using MWR-SPWM technique is compared with traditional inverter by simulation and experiment,and the results show the theoretical analysis is correct.
