PWM
- 采样控制理论中有一个重要结论：冲量相等而形状不同的窄脉冲加在具有惯性的环节上时，其效果基本相同。PWM控制技术就是以该结论为理论基础，对半导体开关器件的导通和关断进行控制，使输出端得到一系列幅值相等而宽度不相等的脉冲，用这些脉冲来代替正弦波或其他所需要的波形。 对不了解PWM的开发人员很有帮助。-Sampling control theory have an important conclusion: the same impulse and different shapes of the

SVPWM
- SVPWM的主要思想是以三相对称正弦波电压供电时三相对称电动机定子理想磁链圆为参考标准，以三相逆变器不同开关模式作适当的切换，从而形成PWM波，以所形成的实际磁链矢量来追踪其准确磁链圆。传统的SPWM方法从电源的角度出发，以生成一个可调频调压的正弦波电源，而SVPWM方法将逆变系统和异步电机看作一个整体来考虑，模型比较简单，也便于微处理器的实时控制。-The source point of view, to generate a frequency modulated voltage sine
单片机产生正弦波
- 通过单片机产生PWM，调节参数寄存器的值，产生不同占空比的PWM信号。若占空比的变化规律是正弦的，则滤波后可得到所需正弦波形。(The PWM is generated by the microcontroller to adjust the value of the parameter register, and the PWM signals with different duty cycles are generated. If the duty cycle is sinusoidal,
