Abstract

　直流電源の両端に接続され且つ共振回路内の一次巻線とコンデンサとに電流を流すスイッチング素子Qp1,Qn1と、各々の放電管点灯装置のバースト調光に位相差を持たせるために、入力された調光用基準信号が所定値になった時に動作を開始し、自己の放電管点灯装置に対して所定の遅延時間を設定する遅延タイマー回路と、コンデンサに対する充放電によりバースト調光用の三角波信号を発生するとともに前記所定の遅延時間だけ調光用基準信号に対して三角波信号に遅延時間を発生する三角波発生器と、三角波発生器で発生した三角波信号とバースト調光信号とを比較した比較出力に基づきスイッチング素子を間欠発振動作させるバースト調光用比較器とを有する。
