    • The present invention relates to an LED luminaire driving circuit with high power factor, comprising: a filter unit, a rectifier unit, a transformer unit, a power switch unit, a zero current detecting unit, a feedback unit, an error amplifier unit, and a power switch driving unit. Particularly, the LED luminaire driving circuit proposed by the present invention does not include any optocoupler feedback circuits, so it is able to effectively reduce the entire circuit manufacturing cost of this LED luminaire driving circuit. Moreover, this LED luminaire driving circuit can selectively work under CCM operation or DCM operation with high power factor (PF˜1), and provide stable output voltage signal and output current signal to load end. In addition, this LED luminaire driving circuit performs excellent stability and current modulation error rate (
    • 本发明涉及具有高功率因数的LED照明器驱动电路,包括:滤波器单元,整流单元,变压器单元,电源开关单元,零电流检测单元,反馈单元,误差放大器单元和 电源开关驱动单元。 特别地,本发明提出的LED灯具驱动电路不包括任何光耦反馈电路,因此能够有效地降低该LED照明器驱动电路的整个电路制造成本。 此外,这种LED灯具驱动电路可以在高功率因数(PF〜1)的CCM操作或DCM操作下选择性工作,并向负载端提供稳定的输出电压信号和输出电流信号。 另外,该LED灯具驱动电路具有优异的稳定性和电流调制误差率(<±3%)。

    • A roll-to-roll electrochemical polish apparatus has a first rotator, a transporting device, a pre-treatment device, an electrochemical polish device, a post-treatment device, and a second rotator. The first rotator serves to rotatably spread out a metal foil roll to a metal foil. The transporting device receives and delivers the metal foil. The pre-treatment device receives the metal foil delivered by the transporting device for cleaning and drying the surface of the metal foil. The electrochemical polish device receives the metal foil outputted from the pre-treatment device for polishing the surface of the metal foil. The post-treatment device receives the metal foil outputted from the electrochemical polish device for cleaning and drying the surface of the metal foil. The second rotator serves to wind the metal foil outputted from the post-treatment device into a finished metal foil roll.
