Abstract:
(EN) [Problem] To provide, inexpensively and via a simple configuration, a power supply device that is capable of improving efficiency. [Solution] A full-wave rectifier circuit 110 generates a DC voltage (pulsating DC voltage) Vdc for which an AC voltage Vac has been rectified. A switching element T131 constituting part of a power supply circuit 130 is on during a fixed on period Mon, and off during a fixed off period Moff (= M – Mon) for individual fixed control cycles M. When the switching element T131 is on, the charge stored in a capacitor C132 causes a current I2 to flow over a path including an inductor L131 and the switching element. When the switching element T131 is off, the electromagnetic energy stored in the inductor L131 causes a return current I3 to flow via a diode D131 and parallel circuits of a capacitor C131 and a load 120. Concurrently, a current I1 is supplied from the full-wave rectifier circuit 110 via an inductor L132 to the capacitor C132. A configuration is adopted such that the current I1 continues to flow to the capacitor C132 during the period that the switching element T131 is off.
(FR) L'invention aborde le problème de réaliser, de manière peu coûteuse et par l'intermédiaire d'une configuration simple, un dispositif d'alimentation électrique qui est capable d'améliorer le rendement. L'invention réalise à cet effet un circuit redresseur pleine onde (110) qui génère une tension continue (tension CC pulsée) Vdc pour laquelle une tension alternative Vac a été redressée. Un élément de commutation (T131) qui constitue une partie d'un circuit d'alimentation électrique (130) est rendu passant pendant une période d'activation fixée Mon, et bloqué pendant une période de désactivation fixée Moff (= M - Mon) pour des cycles de commande fixe individuels M. Lorsque l'élément de commutation (T131) est passant, la charge stockée dans un condensateur (C132) amène un courant (I2) à circuler sur un trajet comprenant une inductance (L131) et l'élément de commutation. Lorsque l'élément de commutation (T131) est bloqué, l'énergie électromagnétique stockée dans l'inductance (L131) produit un courant de retour (I3) qui circule à travers une diode (D131) et les circuits parallèles constitués d'un condensateur (C131) et d'une charge (120). Simultanément, un courant (I1) est délivré au condensateur (C132) par le circuit redresseur pleine onde (110) par le biais d'une inductance (L132). Une configuration est adoptée de telle sorte que le courant (I1) continue de circuler vers le condensateur (C132) pendant la période où l'élément de commutation (T131) est bloqué.
(JA) 【課題】簡単な構成で、安価に、効率を向上させることができる電源装置を提供する。 【解決手段】全波整流回路110は、交流電圧Vacを整流した直流電圧(脈動直流電圧)Vdcを発生する。電力供給回路130を構成するスイッチング素子T131は、固定された制御周期M毎に、固定されたオン期間Monの間オンされ、固定されたオフ期間Moff(=M-Mon)の間オフされる。スイッチング素子T131がオンすると、コンデンサC132に蓄積された電荷により、インダクタL131およびスイッチング素子を含む経路で電流I2が流れる。スイッチング素子T131がオフすると、インダクタL131に蓄積された電磁エネルギーにより、コンデンサC131と負荷120との並列回路およびダイオードD131を介して還流電流I3が流れる。同時に、全波整流回路110からインダクタL132を介してコンデンサC132に電流I1が供給される。スイッチング素子T131がオフしている期間中、コンデンサC132に電流I1が流れ続けるように構成されている。
