摘要
在SPWM逆变器中,影响逆变器波形输出的几个主要因素有温漂、死区效应以及稳压反馈。这些因素的控制的情况影响逆变器输出基波电压、谐波成分,输出波形的毛刺情况以及反馈电路的稳压效果,从而直接影响逆变器的稳定性。文章对温漂效应、死区效应进行研究,通过对硬件中不同电路模块的改进,并在此基础上对其电路模块进行仿真,同时通过搭建SPWM硬件驱动模块进行验证,从而论证此研究基础上的SPWM逆变器的优势。
In SPWM inverters, several major factors that influencing the inverter output waveform with temperature drift, the dead time effect and stabilizing voltage feedback. Influence of inverter output fundamental voltage, harmonic composition control of these factors, the burr of output waveform and feedback circuit of the voltage stabilizing effect, which directly affect the stability of the inverter. In this paper, the dead time effect of temperature drift effect, through the improvement of the different circuit module in hardware, and on the basis of the circuit module of simulation, at the same time set up through the SPWM hardware driver module is verified, which proves the SPWM inverter based on the study of the advantages of the.
