Abstract:
(EN) The present invention is provided with: a rectification circuit (3) which rectifies AC power; a DC conversion circuit (30) which inhibits higher harmonics of a current and improves the power factor, and converts the power outputted from the rectification circuit (3) into DC power, and supplies said DC power to a light source; and a control unit (9) which controls the DC conversion circuit (30). The DC conversion circuit (30) is provided with: a smoothing capacitor (6); a MOSFET (51) which is disposed between the smoothing capacitor (6) and the rectification circuit (3); and a coil (52) through which the current outputted from the rectification circuit (3) flows. The control unit (9) sets the MOSFET (51) in an off state from the point in time at which the current flowing through the coil (52) becomes zero, until a delay time set in the control unit (9) elapses, and turns the MOSFET (51) on when the delay time has elapsed.
(FR) La présente invention comprend : un circuit de redressement (3) qui redresse une puissance CA ; un circuit de conversion de CC (30) qui inhibe des harmoniques supérieures d'un courant et améliore le facteur de puissance, et convertit la puissance délivrée en sortie par le circuit de redressement (3) en puissance en CC, et fournit ladite puissance en CC à une source de lumière ; et une unité de commande (9) qui commande le circuit de conversion de CC (30). Le circuit de conversion de CC (30) comprend : un condensateur de lissage (6) ; un MOSFET (51) qui est disposé entre le condensateur de lissage (6) et le circuit de redressement (3) ; et une bobine (52) à travers laquelle s'écoule le courant délivré en sortie par le circuit de redressement (3). L'unité de commande (9) met le MOSFET (51) dans un état inactif à partir du moment où le courant s'écoulant à travers la bobine (52) devient nul, jusqu'à ce qu'un temps de retard défini dans l'unité de commande (9) s'écoule, et active le MOSFET (51) lorsque le temps de retard s'est écoulé.
(JA) 交流電力を整流する整流回路(3)と、電流の高調波を抑制して力率を改善すると共に整流回路(3)から出力される電力を直流電力に変換して光源に供給する直流変換回路(30)と、直流変換回路(30)を制御する制御部(9)とを備え、直流変換回路(30)は、平滑コンデンサ(6)と、平滑コンデンサ(6)及び整流回路(3)の間に配置されるMOSFET(51)と、整流回路(3)から出力される電流が流れるコイル(52)とを有し、制御部(9)は、コイル(52)に流れる電流がゼロになった時点から、制御部(9)に設定された遅延時間が経過するまでMOSFET(51)をオフ状態にさせて、遅延時間が経過したときにMOSFET(51)をオンさせる。
