| 摘 要： | 提出了一种适用于小功率高强度气体放电灯的电子镇流器。它由一个单级功率因数变流器和一个低频逆变器结合而成,采用了恒功率控制,使得灯功率基本保持恒定,通过采用低频方波点灯的方法有效地克服了声谐振的发生,并通过对一个70W 金卤灯的实验证明了该方案的可行性。

| Abstract: | A novel single stage electronic ballast for low-wattage High-Intensity Discharge(HID) lamps is presented in this paper.The ballast is obtained from the integration of a single-stage power factor correction converter and a low-frequency inverter.The output power to the lamps is constant approximately due to constant power control.The proposed ballast provides low-frequency square-wave current to the lamp to avoid acoustic resonances.A prototype for a 70 W metal halide lamp verifies its feasibility. |
