镇流器 Electrical ballast
（重定向自Electronic ballasts）
安定器，是指为了克服气体放电型电光源的负阻特性，使之能够正常工作而加入的配套使用的电器设备。传统的镇流器一般是一个由漆包线和由硅钢片组成的铁芯绕制而成的电感，并且常常还需要与一个启动器配套使用。传统电感式镇流器的一些缺点使它正在被日益发展成熟的电子安定器（Electronic Ballast）所取代。

An electrical ballast is a device intended to limit the amount of current in an electric circuit. A familiar and widely used example is the inductive ballast used in fluorescent lamps, to limit the current through the tube, which would otherwise rise to destructive levels due to the negative differential resistance artifact in the tube's voltage-current characteristic.
