Description
時刻T1でスイッチング素子Q1がオフすると、リアクトルLrに蓄えられた励磁エネルギが放電電流ILrとして、入力側とアクティブクランプ回路ACに流れる。放電電流ILrは、第2の巻線L2を通過することになり、このときアンペアターン則によって第1の巻線L1にはILr・(Ns/Np)の電流が流れ始める。すなわち入力側に放電電流ILrを戻すことになり、入力電流Iinは減少し始める。
放電電流ILrによってコンデンサCaが充電され続け、スイッチング素子Q1のソース・ドレイン間電圧Vdsが上昇しきった後、コンデンサCbの放電が進み、コンデンサCbの電圧が、ダイオードDbの順方向電圧Vfbによって−Vfbでクランプされると、ダイオードDbに放電電流ILrが流れ始める。
ダイオードDbに電流が流れている間に、時刻T3でスイッチング素子Q2がオンされ、スイッチング素子Q2はソースチャネルからドレインチャネルへ放電電流ILrを流し始める。そしてリアクトルLrの放電エネルギが放出を終えると、コンデンサC1の電圧Vc1によって、リアクトルLの第1の巻線L1に(Vc1−Vin)が印加されると共に、{(Vc1−Vin)(Ns/Np)+Vc1}でリアクトルLr及びトランスTの1次巻線TL1は励磁され始める。励磁ループは、GND−コンデンサC1−スイッチング素子Q2−第2の巻線L2−コンデンサC−1次巻線TL1−リアクトルLr−GNDの向きである。
時刻T3の状態を継続し、リアクトルLr及び1次巻線TL1は励磁され続ける。
時刻T5でスイッチング素子Q2がオフになり、励磁されていたリアクトルLrから放電電流ILrが流れ始める。放電電流ILrの経路は、リアクトルLr−コンデンサCa−第2の巻線L2−コンデンサC―1次巻線TL1−リアクトルLrであり、放電電流ILrによりコンデンサCaの電荷が放電され始める。また、スイッチング素子Q2がオフになったことで、コンデンサCbはコンデンサC1の電圧Vc1によって充電され始める。
リアクトルLrの放電電流ILrによってコンデンサCaが放電され続け、コンデンサCaの電圧が、ダイオードDaの順方向電圧Vfaによって−Vfaでクランプされると、ダイオードDaにリアクトルLrの放電電流ILrが流れ始める。
ダイオードDaに電流が流れている間に、スイッチング素子Q1がオンになり、スイッチング素子Q1は、ソースチャネルからドレインチャネルに放電電流ILrを流し始める。
リアクトルLrの放電エネルギが放出を終えると、第1の巻線L1に入力電圧Vinが印加される。これにより、第2の巻線L2にはVin・(Ns/Np)の電圧が発生し、トランスTの1次巻線TL1には、コンデンサCの電圧Vinとともに、Vin・(Ns/Np)の電圧が印加される。以上の動作が繰り返される。
