| description | To provide a backup power supply system that achieves downsizing of a circuit.SOLUTION: A first transistor Tr13 and a second transistor Tr14 are connected in series between a source and a reference potential of a second field effect transistor SW3, and a respective emitter is connected to a gate of the second field effect transistor SW3. A first drive circuit 21 operates the second field effect transistor SW3 in an active region by outputting a driving signal S12 based on a current command value S11 and a current value of current flowing through the second field effect transistor SW3 to bases of the first and the second transistors Tr13 and Tr14. A second drive circuit 22 has a first switching element Q14 connected between a corrector and the base of the second transistor Tr14. When the first switching element Q14 is turned ON by an ON signal Son inputted from a control unit 10, the second field effect transistor SW3 is turned ON.SELECTED DRAWING: Figure 3
【課題】回路の小型化を図ったバックアップ電源システムを提供する。【解決手段】第１のトランジスタＴｒ１３と第２のトランジスタＴｒ１４とは、第２の電界効果トランジスタＳＷ３のソースと基準電位との間に直列に接続され、第２の電界効果トランジスタＳＷ３のゲートにそれぞれのエミッタが接続される。第１ドライブ回路２１は、電流指令値Ｓ１１と第２の電界効果トランジスタＳＷ３に流れる電流の電流値とに基づく駆動信号Ｓ１２を第１及び第２のトランジスタＴｒ１３，Ｔｒ１４のベースに出力することによって第２の電界効果トランジスタＳＷ３を能動領域で動作させる。第２ドライブ回路２２は、第２のトランジスタＴｒ１４のコレクタ・ベース間に接続された第１のスイッチング素子Ｑ１４を有する。制御部１０から入力されるオン信号Ｓｏｎによって第１のスイッチング素子Ｑ１４がオンになると第２の電界効果トランジスタＳＷ３がオンになる。【選択図】図３ |
