逆变器SPWM控制电路的研究与设计
资料介绍
本文依据SPWM控制原理。以逆变器控制电路为研究对象，通过分立电路设计出SPWM电路。调制波为50Hz正弦波。载波为10KHz--角波。输出SPWM波频率为20KHz。实验证明该电路稳定性好。有效克服了温飘，反馈迅速。且成本低，输出实现倍频效应，对逆变器控制的理解和学习有很好的指导作用。具有较高的实用价值。
The principle of the driver circuit of an inverter is introduced in this paper. A SPWM control circuit is designed with discrete components. The frequency of triangular wave is 10KHz, the sine wave is 50Hz, and the SPWM is 20KHz. The experimental results show that this method can work well. Temperature drift is overcome. And the cost is low. The output frequency is doubled. In addition, this paper helps us understanding the SPWM control circuit better. And the pragmatic value of this design is high.
