ripple frequency

基本解释

Synchronous rectification produces a ripple frequency twice that of the excitation frequency and thus is easier to remove with a lowpass filter.
同步稳压产生两倍激励频率纹波频率，因此更容易被低通滤波器去除。
The design eliminates the use of the large-valued filter capacitors you usually find in a switching regulator, because there is no need to smooth out high-frequency ripple in the LED current.
这种设计去除了通常在开关电源附近的大滤波电容，因为没有必要对LED电流的高频谐波进行平滑处理。
It features in low torque ripple, low flux ripple and fixed switching frequency.
它具有开关频率恒定，转矩和磁链波动小等特点。
