Description
さらに、本発明の短絡保護回路220では、半導体スイッチが用いられるが、これは、本発明の電圧切り替え時の期間が数サイクルと短いために、機械的スイッチでは動作遅れがあり時間がかかってしまうからである。
なお、トライアックTRC2がゲート信号の無くなってから自然転流でOFFするまでの時間は、正弦波電圧がゼロとなる時間が不確定であるために、短絡しないように余裕をみてOFF−OFF時間を確保しなければならないので、その分だけ時間が長くなってしまうという問題がある。
なお、図5は、このような動作例(1)及び動作例(2)についてのタイムチャート図を示すものである。
また、電圧調整用直列変圧器T1、T2の2次巻き線側に大きな過電圧が発生することもないから、2次巻き線側に接続された半導体スイッチとしてこの過電圧に耐えられる素子を選定することもなく、この過電圧に対する電圧抑制のための保護回路などの措置を取ることもない。
また、本発明は、自然転流消弧タイプの半導体スイッチで、例えばトライアック又は逆並列接続されたサイリスタを使用する場合に有効であるが、このタイプの半導体スイッチの他に、機械的スイッチを使用する場合にも適用可能であり、また自己消弧形半導体スイッチに適用してもよい。これらは、電圧調整部の半導体スイッチと短絡保護回路の半導体スイッチの両方又はいずれか一方の適用でも良い。さらに、線路電圧引き込み点は、直列変圧器の入力側でも出力側でもよく、短絡保護回路は、短絡電流が流れる経路であれば、その経路のどの位置に設けても利用可能である。その他、短絡保護回路220の構成は、抵抗器ではなくリアクトル等でもよい。

Claims (1)
- 電圧調整用直列変圧器と、半導体スイッチのオンオフを制御する制御回路と、該制御回路からの信号がOFFしても交流電圧の逆電圧が負荷されるまで導通している自然転流消弧タイプの半導体スイッチを有する電圧切替回路から成る電圧調整部とを備えた電圧調整装置であって、前記電圧切替回路の電圧取出し側に、短絡電流を抑制する制限抵抗と該制限抵抗をショートする半導体スイッチとから成る短絡保護回路を設けたことを特徴とする電圧調整装置。
