Title (EN) POWER SUPPLY DEVICE
(FR) DISPOSITIF D'ALIMENTATION ÉLECTRIQUE
(JA) 電源装置
Abstract:
(EN) The present invention addresses the problem of providing a power supply device with which externally emitted noise can be decreased in a preferable manner. The power supply device 100 is a power supply device to which alternating-current power is input from an external power supply, and which outputs high frequency power to a load apparatus. The power supply device 100 is provided with: a substrate on which a filter circuit, a rectification circuit, a step-up circuit, and a fluorescent tube excitation circuit are electrically connected in order and mounted; and a shield case in which the substrate is housed. A shield member for decreasing radiation noise is provided between the filter circuit and the rectification circuit, or in the filter circuit.
(FR) Le problème décrit par la présente invention est de pourvoir à un dispositif d'alimentation électrique qui puisse diminuer d'une manière préférable le bruit émis à l'extérieur. Le dispositif d'alimentation électrique 100 est un dispositif d'alimentation électrique auquel de la puissance en courant alternatif est appliquée à partir d'une alimentation électrique externe, et qui délivre de la puissance haute fréquence à un appareil formant charge. Le dispositif d'alimentation électrique 100 est pourvu : d'un substrat sur lequel un circuit de filtre, un circuit de redressement, un circuit élévateur et un circuit d'excitation de tube fluorescent sont électriquement connectés dans cet ordre et montés ; et d'un boîtier de blindage dans lequel le substrat est logé. Un élément de blindage servant à diminuer le bruit de rayonnement est disposé entre le circuit de filtre et le circuit de redressement, ou dans le circuit de filtre.
(JA) 本発明の課題は、外部に放出されるノイズの低減を良好に行うことができる電源装置を得ることである。電源装置100は、外部電源から交流電力が入力されるとともに、高周波電力を負荷器具に出力する電源装置であって、フィルタ回路と、整流回路と、昇圧回路と、蛍光管励振回路とが電気的に順に接続する状態で実装される基板と、該基板を収納するシールドケースとを備え、該フィルタ回路と該整流回路との間、または該フィルタ回路内に放射ノイズを低減するシールド部材を設けている。
