指令生成PWM,可产生分辨率很高的PWM,但会影响其他任务运行,一般用在较简单的控制中 定时器产生PWM 部分单片机本身具有PWM模块功能 定时器 1.定时器功能 定时、输出比较(PWM)、输入捕获(测量脉冲宽度)、互补输出 2.定时器分类 基本定时器、通用定时器、高级定时器 3.定时器资源 F103系列有两个高级定时器TIM1和TIM8...
Fig. 3 : Principle of the delta PWM. The output signal (blue) is compared with the limits (gn). These limits correspond to the reference signal (red), offset by a given value. Every time the output signal reaches one of the limits, the PWM signal changes state. Sigma-Delta The output...

现在改成LL_TIM_OCMODE_PWM2,那么电平就翻转.PWM1通过改变其他数值,也做不到PWM2效果. 当然,除了PWM模式外,还有其他几个OC模式. #defineLL_TIM_OCMODE_FROZEN((uint32_t)0x00000000U)/*!<The comparison between the output compare register TIMx_CCRy and the counter TIMx_CNT has no effect on the ...

SPWM(Sinusoidal PWM)法是一种比较成熟的,目前使用较广泛的PWM法.前面提到的采样控制理论中的一个重要结论: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.SPWM法就是以该结论为理论基础,用脉冲宽度按正弦规律变化而和正弦波等效的PWM波形即SPWM波形控制逆变电路中开关器件的通断,使其输出的脉冲...
