【摘要】 目前国外有不少公司都在研制高强度放电(HID)灯电子镇流器,但普遍存在的问题是可靠性差、易损坏、成本高。虽然HID灯电子镇流器节能效果显著,但推广应用不够。研究了主电路产生70 W功率的高频信号以点燃HID灯,以及声共振抑制电路。重点解决的关键问题是利用L6562专用集成电路研制有源功率因数校正电路及抑制声共振电路。更多还原

【Abstract】 At present,the high intensity discharge(HID) lamps electronic(ballast developed by many foreign companies have the shortcomings of poor reliability,easy to damage and high cost.Although the high intensity discharge(HID) lamps electronic ballast can save energy remarkably,but its application is not wide.The main circuit was studied,which could produce 70 W power of high frequency signals to light the lamp and the inhibit sound resonance circuit.The key problems was to use special integrated circuit L6562 to develop active power factor correction circuit,inhibit sound resonance circuit and lamp start-up circuit.更多还原
