Description
Claims (1)
- 交流電源電圧を全波整流する整流器と;
前記整流器で全波整流された電圧をオンオフ制御して負荷に流れる電流の導通を制御するメインスイッチと;
前記整流器で全波整流された電圧のゼロクロスを検出するゼロクロス検出部と;
前記ゼロクロス検出部で検出されたゼロクロスのタイミングで前記メインスイッチをオンするとともに一定の点弧角でオフし、前記整流器で全波整流された電圧を逆位相制御する制御部と;
前記ゼロクロス検出部での前回のゼロクロスの検出時点から所定時間は次のゼロクロスの検出を阻止するゼロクロス検出阻止部と;を備え、前記ゼロクロス検出阻止部が次のゼロクロスの検出を阻止する所定時間は、前記メインスイッチのオン時間より長いことを特徴とする逆位相制御装置。
