Description
交流電力を直流電力に変換する電力変換装置であって、
サイリスタを含む整流部と、
前記整流部の後段に設けられるコンデンサと、
前記サイリスタの点弧を制御する制御部と、
を備え、
前記制御部は、
前記交流電力の電圧がゼロであるゼロクロス点に到達したときから、前記交流電力の所定周波数に応じて定められた所定時間後に、前記サイリスタの点弧を行うことで、前記コンデンサに電力を供給させるとともに、前記サイリスタの点弧を行う度に前記所定時間を短く設定し、
前記交流電力の周波数が、前記所定周波数から変動した場合、前記所定周波数に応じて定められた所定時間後に前記サイリスタの点弧を行わないように制御する。
電力変換装置100の力率改善部130を正常に動作させるため、コンデンサ134の電圧値を所望の電圧値にプリチャージする必要がある。しかしながら、コンデンサ134が十分にチャージされていない場合、コンデンサ134の電圧値と、交流電力の電圧値との差分が過剰となる。その結果、当該差分に起因して、突入電流が過剰になり、周辺回路に影響を及ぼす可能性がある。
