Abstract

　エレベータのブレーキシステムにおいては、電磁コイルを有するブレーキ装置の制動力の発生により、かごの移動が制動される。制動力は、電磁コイルへの通電の停止により発生し、電磁コイルへの通電により停止される。電磁コイルへの通電を行うための動作用電圧は、インバータによって入力電圧が変換されることにより発生する。インバータは、動作用電圧の波形が正と負との間で交互に切り替わる波形となるように、ブレーキ制御装置により制御される。インバータと電磁コイルとの間の電気的接続は、第１開閉器により開閉可能になっている。動作用電圧が周期的に零電圧になるので、第１開閉器の小形化を図ることができる。また、動作用電圧がブレーキ制御装置の制御により調整されるので、ブレーキ装置の動作をより細かく制御することができる。
