參考設(shè)計和開發(fā)工具包可以顯著加快您的下一個電機(jī)控制項(xiàng)目

?

　　你可能知道，電機(jī)控制應(yīng)用已經(jīng)使用MCU多年，但你可能不知道，用于電機(jī)控制的非常早的MCU實(shí)際上是針對功率逆變器產(chǎn)業(yè)市場，設(shè)計的直流電源轉(zhuǎn)換為AC曾經(jīng)認(rèn)為波形輸出功能的脈沖寬度調(diào)制（PWM）已解決電機(jī)控制的設(shè)計潛力，事情迅速起飛。今天，單片機(jī)用于幾乎所有的電機(jī)控制應(yīng)用的想象；和在所附的電源模塊，采用新的控制算法和功率因數(shù)校正，電機(jī)效率明顯提高。

　　估計與電機(jī)有關(guān)的電力彌補(bǔ)了世界能源的百分之20以上的使用，很容易看到，提高效率是所有新的電機(jī)控制設(shè)計的一個主要焦點(diǎn)。這些新的算法比傳統(tǒng)的方法要復(fù)雜得多，但是，MCU制造商已經(jīng)創(chuàng)建了完整的開發(fā)工具包和參考設(shè)計，以加快這些重要應(yīng)用的發(fā)展。本文將回顧最近推出的電機(jī)控制開發(fā)工具包的采樣，給你一個堅實(shí)的背景，選擇套件，是適合您的下一個應(yīng)用程序。

　　A good place to start

?

　　You might not know it， but a good place to start your search for the right development kit for your next design is with the Digi-Key Reference Design Library. The library， as shown in the screenshot （Figure 1） below， is organized by target application， such as AC/DC and DC/DC Conversion， Audio Amplifiers， Energy Harvesting， Lighting， and Motor Control. If you select an application， like motor control， the filter window comes up， as shown on the right side of the figure， with several columns of items you can specify during your search. For example， if you want a motor-control reference design for a Three-Phase Induction Motor with Overcurrent Protection and Power Factor Correction you will get several hits showing kits from Texas Instruments， Microchip， and STMicroelectronics. You can look over a summary of the kits’ features， data sheets， and users’ guides to find the right one for your application. We’ll now use the Digi-Key Reference Design Library to explore the available kits for some common motor-control applications.
