ripple frequency

基本解釋

Synchronous rectification produces a ripple frequency twice that of the excitation frequency and thus is easier to remove with a lowpass filter.
同步穩(wěn)壓産生兩倍激勵頻率紋波頻率，因此更容易被低通濾波器去除。
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.
這種設計去除了通常在開關電源附近的大濾波電容，因爲沒有必要對LED電流的高頻諧波進行平滑処理。
It features in low torque ripple, low flux ripple and fixed switching frequency.
它具有開關頻率恒定，轉矩和磁鏈波動小等特點。
