    絶縁型CANシステムにおけるエミッションの低減とイミュニティの向上

    現在では、異なる電圧で動作しているシステムが増えているため、絶縁型CANトランシーバは、エレベーターから電気自動車、船舶システムに至る幅広い分野で必要な要素になっています。 これらのトランシーバは、コントローラ・エリア・ネットワーク(CAN)規格におけるプライオリタイゼーション機能とアービトレーション機能を、絶縁によるメリット(グランドループの除去、電位差への耐性、同相過渡電圧耐性など)と統合することにより、システム内の2つの電圧ドメイン間で信頼性の高い通信を維持するのに役立ちます。 非絶縁型C...

    絶縁型RS-485トランシーバの設計に関するよくある質問

    オンラインの技術質問ページ、 TI E2E™ Community にいただいた質問から、 絶縁型RS-485トランシーバ の設計課題に関する、よくある質問リストを作成しました。このリストから、RS- 485において信号および電力を絶縁する際に有益な見解を得ていただければ幸いです。 1. RS-485 バスの絶縁が必要なのはどのような時ですか? 絶縁は、システム内の2つの部品間における直流電流(DC)と不要な交流電流(AC)の流れを阻止する一方、2つの部品間の信号と電力の転送は行います。一般的に、絶縁は電気部品や人を危険な電圧や電流サージから保護します。人の安全のための絶縁を強化絶縁と呼びます。絶縁により、長距離のノード間通信において一般的なグラウンドループは形成されません。また、絶縁により、RS-485規格の規定値よりも大きい接地電位差を有するノード間での通信が可能になります。 2. RS-485 バスには何個のノードを接続できますか...

    Advantages of using nonisolated DC/DC power buck modules in DAQ applications

    (Note: Sreenivasa Kallikuppa co-authored this blog post.) In a previous post, “ Enhancing DAQ performance for grid protection, control and monitoring equipment using DC/DC power modules ,” we discussed how power modules offer lower electromagnetic interference (EMI) and output ripple, thus improving overall data acquisition (DAQ) performance. In this post, my colleague Sreenivasa and I will cover some of...

    MSP430マイコン:スマート・アナログ・コンボを用いた煙感知器の設計

    電気式の火災警報器や熱感知器などの煙感知器は、1890年代に初めて発明されました。この発明は長年にわたって改良が重ねられ、イオン化式や光電式の煙感知器のような、より高度な設計に至っています。 現代の電子工学により、こういった煙感知器の設計は、シンプル、安定的、高い費用対効果となっています。煙感知器がAC電源式である場合は、一般的に9Vのバックアップ・バッテリが搭載されています。このため、煙感知器の設計は、AC/DCの電力供給量を少なくしてバックアップ時のバッテリ寿命が長くなるように、低消費電力を...

    Now that you have isolated your CAN signals, what about power?

    As I covered in my previous post , the use of the isolated Controller Area Network (CAN) standard is increasing in both industrial and automotive applications. With higher voltages being used in these end applications, isolated communications are becoming imperative when protecting the low-voltage microcontroller while also reducing noise. But just adding an isolated CAN transceiver is not enough. Isolated power supplies...
