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)壓產(chǎn)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(shè)計去除了通常在開關(guān)電源附近的大濾波電容，因為沒有必要對LED電流的高頻諧波進(jìn)行平滑處理。
It features in low torque ripple, low flux ripple and fixed switching frequency.
它具有開關(guān)頻率恒定，轉(zhuǎn)矩和磁鏈波動小等特點。
