Description
このスイッチング電源装置によれば、入力端子TIN1と入力端子TIN2との間に印加された所定電圧(Vin)の直流入力電力が、スイッチS1〜S4からなるフルブリッジ回路のスイッチング動作により交流電力に一旦変換されてトランスTの1次巻線L1に供給される。
ここで、前記スイッチング回路は、例えば、フルブリッジ回路、ハーフブリッジ回路、一石フォワード回路、RCC回路の何れかであることを特徴とする。
また、前記第1整流器に代えてトランジスタ(スイッチ)を備え、該トランジスタにより前記トランスの2次巻線に誘起される交流電力を同期整流するように構成してもよい。
この構成によれば、スイッチング電源装置の主整流器のカソードに発生するサージが、本サージ吸収回路が備える整流器を介してコンデンサに供給され、このコンデンサを充電する。コンデンサは負荷に動作電力を供給する。
先ず、図1を参照して、本発明の実施形態に係るスイッチング電源装置が備えるサージ吸収回路の原理を説明する。
図1において、2次巻線L2は、前述の図3に示すトランスTの2次巻線L21,L22に相当する。ダイオードD2は、前述の図3に示す2次側に設けられた主ダイオードD21,D22に相当する。ダイオードD3およびコンデンサCは、本発明に係るサージ吸収回路を構成する。所定負荷Fは、コンデンサCを補助電源として動作する任意の装置であり、その内容は特に限定されない。
図2に示すスイッチング電源装置は、図1に示す構成と比較して、ダイオードD31,32、電解コンデンサC、負荷Fを更に備えている。このうち、ダイオードD31,D32及び電解コンデンサCは、このスイッチング電源装置のサージ吸収回路を構成する。
スイッチS1〜S4からなるフルブリッジ回路が所定のスイッチング動作(周知のスイッチング動作)を実施することにより、入力端子TIN1を介して供給された直流入力電力が交流電力に変換され、トランスTの1次巻線L1に供給される。これにより1次巻線L1には交番電流が発生し、トランスTの2次巻線L21,L22には、互いに逆位相の交流電力がそれぞれ誘起される。この2次側に誘起された交流電流は主ダイオードD21,D22によって整流された後、出力巻線L23及び出力端子TOUT1を介して外部に出力される。
なお、負荷Fには主電源も供給されるが、電解コンデンサCを補助電源とすることにより、主電源の不足分が電解コンデンサCから適宜補充される。
例えば、上述の実施形態では、トランスTの1次側のスイッチング回路をフルブリッジ回路として構成したが、これに限定されず、ハーフブリッジ回路、一石フォワード回路、RCC回路など、1次側のスイッチング回路の形式は問わない。
また、上述の実施形態では、2次側に主ダイオードD21,D22を設け、これら主ダイオードにより整流するものとしたが、これら主ダイオードに代えてトランジスタ等のスイッチ手段を設け、これにより、いわゆる同期整流を行うものとしてもよい。この場合、同期整流の際にトランジスタに発生するサージがダイオードD31,D32を介して電解コンデンサCに吸収されるので、同様に電源効率を改善することが可能になる。
また、電解コンデンサCに代えて、他の形式のコンデンサを採用してもよい。
