常見例句雙語例句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(lì)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(jì)去除了通常在開關(guān)電源附近的大濾波電容，因爲(wèi)沒有必要對(duì)LED電流的高頻諧波進(jìn)行平滑処理。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(dòng)小等特點(diǎn)。 返回 ripple frequency
