| description | To provide an optical communication system capable of synchronizing update timings of data transmitted to all power conversion circuits with a simple configuration.SOLUTION: In a power conversion device in which a plurality of power conversion cells (300) having controllers and power conversion circuits are provided and a central control unit 200 and the plurality of power conversion cells are daisy-chain connected through optical cables forming double loops 1, 2, the controllers (3011 to 3015) each have a function for demodulating and holding a conversion circuit control signal in a communication frame for serial communication to be transmitted, and a function for calculating, as a delay time, a half of a difference between a reception start time of the subsequently received communication frame and a previous reception time of the loop 1 or 2, determining a data update timing on the basis of the delay time and the reception time of the communication frame, and outputting the conversion circuit control signal to the power conversion circuits (3021 to 3025) at this timing.SELECTED DRAWING: Figure 2
【課題】簡単な構成により、全ての電力変換回路に送信するデータの更新タイミングを同期させることができる光通信システムを提供する。【解決手段】制御器および電力変換回路を備えた電力変換セル（３００）を複数設け、中央制御装置２００と複数の電力変換セルの間を、ループ１、２の二重ループを形成する光ケーブルによってデイジーチェーン接続した電力変換装置において、制御器（３０１1～３０１5）に、伝送されるシリアル通信用通信フレーム内の変換回路制御信号を復調し保持する機能と、ループ１又はループ２のうち後に受信した前記通信フレームの受信開始時刻と先に受信した時刻の差の半分を遅延時間として求め、その遅延時間と前記通信フレームの受信時刻に基づいてデータ更新タイミングを決定し、そのタイミングで前記変換回路制御信号を電力変換回路（３０２1～３０２5）へ出力する機能とを持たせた。【選択図】 図２ |
