模式的小型智能步進(jìn)電機(jī)驅(qū)動(dòng)器和控制器 IC，是這款模擬唱機(jī)的解決方案。除了 StealthChop 之外，Trinamic 還改進(jìn)了電壓模式操作并將其與電流控制相結(jié)合。為了大限度地減少電流波動(dòng)，TMC5130A-TA 芯片的驅(qū)動(dòng)器根據(jù)電流反饋調(diào)節(jié)電壓調(diào)制。這允許系統(tǒng)根據(jù)電機(jī)參數(shù)和工作電壓進(jìn)行自我調(diào)整。

了由直流控制環(huán)路的調(diào)節(jié)算法引起的小振蕩。由于SpreadCycle 和其他電流調(diào)節(jié)斬波器原理總是對(duì)線圈電流測(cè)量做出逐個(gè)周期的反應(yīng)，因此復(fù)雜系統(tǒng)中總是存在幾毫伏的噪聲，以及內(nèi)部?jī)蓚€(gè)線圈之間的電磁耦合。導(dǎo)致產(chǎn)生的電機(jī)電流的微小變化，從而影響斬波器。

下圖比較了電壓控制的 StealthChop 和電流控制的 SpreadCycle。StealthChop 的過(guò)零行為是的：當(dāng)電流值的符號(hào)從正變?yōu)樨?fù)或反之亦然時(shí)，沒(méi)有平臺(tái)，而是零電流水平的直線交叉，因?yàn)殡娏魇腔谡{(diào)制的 PWM 占空比。在 50% PWM 占空比下，電流實(shí)際上為零。
