Abstract

　直流電力を交流電力に変換して放電管に供給する交流変換回路は、交流電源側に配置された１次巻線と放電管側に配置された２次巻線とにより電気的に絶縁する主変圧器と、交流電源側に配置されたIC1と、交流電源側に配置されIC1により駆動され直流電力により主変圧器の１次巻線に電流を流すブリッジ構成の複数のスイッチング素子Qn1～Qn4と、放電管側に配置され放電管に流れる電流をＰＷＭ制御するためのデューティ比が５０％未満の同一パルス幅で且つ略１８０度の位相差を持つ１対の矩形波信号を発生するIC2と、IC2からの１対の矩形波信号をIC1に送出する１以上の信号伝達絶縁素子とを有し、IC1は１以上の信号伝達絶縁素子からの１対の矩形波信号に基づき複数のスイッチング素子を駆動して主変圧器の２次巻線から放電管に正負対称の交流電力を供給する。
