摘要
介绍了一种高品质单相正弦波输出逆变电源的设计。研究了通过中断功率通量和调节占空比的方法来改变驱动电压脉冲宽度,调整和稳定输出电压,并设计了具体的数字控制电路。通过试验样机的调试和试验,验证了设计合理可行,电路工作稳定,输出电压波形平滑,具有较好的正弦度。
A modified single-phase sinusoidal inverter is introduced in this paper. The methods of intermitting power flux and changing duty-cycle can change pulse width of drive voltage that adjust and rectify output voltage ultimately. The paper designed digital control circuit; final presented the inverter power supply prototype and got experimental results. The results demonstrate that the project is reasonable, can get ideal output waveforms.
