Abstract: front page image
(EN)A switching power supply is provided with a first switch (SW1) arranged between nodes (N21, N31), a second switch (SW2) installed between nodes (N11, N22), a capacitor (C1) disposed between the second switch and the node (N22), a third switch (SW3) arranged between the nodes (N21, N12), a delay circuit (L1) which is disposed between the third switch (SW3) and the node (N12) and delays current for charging the capacitor (C1) and a first diode (D1) arranged between the nodes (N13, N22). In the first diode (D1), a node (N13)-side is a cathode.
(FR)Une alimentation à commutation est munie d'un premier commutateur (SW1) disposé entre des nœuds (N21, N31), d'un second commutateur (SW2) installé entre des nœuds (N11, N22), d'un condensateur (C1) disposé entre le second commutateur et le nœud (N22), d'un troisième commutateur (SW3) disposé entre les nœuds (N21, N12), d'un circuit de retard (L1) qui est disposé entre le troisième commutateur (SW3) et le nœud (N12) et qui retarde le courant de charge du condensateur (C1) et d'une première diode (D1) disposée entre les nœuds (N13, N22). Dans la première diode (D1), un côté nœud (N13) est une cathode.
(JA)本発明は、ノードN21とN31との間に設けられた第1スイッチSW1と、ノードN11とN22との間に設けられた第2スイッチSW2と、第2スイッチとノードN22との間に設けられたキャパシタC1と、ノードN21とN12と、の間に設けられた第3スイッチSW3と、第3スイッチSW3とノードN12との間に設けられ、キャパシタC1を充電させるための電流を遅延させる遅延回路L1と、ノードN13とN22との間に設けられた第1ダイオードD1と、を具備し、第1ダイオードD1は、ノードN13側がカソードであるスイッチング電源である。
