It looks from the manual that the chip supports dithering using the lower 4 bits of the duty cycle, but I don’t seem to see support in the API for this. Am I missing it?leafmuncher Posts: 5 Joined: Thu Apr 06, 2023 6:47 pm Re: ESP32 S3 LEDC and PWM dithering...
Dithering is performed by repetitively adding and subtracting first and second dither values form the desired output currents; or, repetitively adding a first dither value, adding a zero dither value and subtracting a second dither value form the desired output currents. The dither value can be ...
A8660 旨在满足汽车、工业和消费类应用的电源要求,包括所有控制和保护电路,从而生成提供大电流的稳健 PWM 控制器。 A8660 包括 PWM 频率抖动,已被证明可降低 EMI/EMC。当转换器退出低 VIN 压降状态时,软恢复功能可防止输出电压过冲。对于高电流、低频设计(<520 kHz),可以将外部时钟应用于 SYNCIN 引脚以移位 PWM...

看到哪记到哪 抖动模式(Dithering mode) 在查看手册的时候发现了这个模式,第一次看没看懂(可能是太困了),今天又看了一遍手册,大致理解了这个模式的作用。 抖动模式的功能就是增加PWM的分辨率。 手册的介绍是这样的: 抖动模式 PWM的有效分辨率可以通过启动抖动模式来提高,使能TIMx_CR1寄存器中的DITHEN位来启动抖动...
摘要：A pulse width modulated (PWM) inverter is controlled by repetitively changing or dithering desired output currents for the inverter to ensure that it is unable to settle into zero states which result in lack of torque control when the inverter is used to control an AC motor. Dithering is...
