1 荧光灯中用的逆变器是什么样的逆变器技术已广泛地普及到家电领域,其名称也已为一般人所熟知。它在通常的应用领域中以频率可变等可控性作为特征而使用的情况较多,但照明用的逆变器,特别是荧光灯所用的逆变器却具有另外的明显特征。荧光灯是将电气的输入变换成光的输出的变换器。通过在高频下点灯,能使变换效率大幅度提高。这一点已成为照明用逆变器的重要特征。例如,使荧光灯在超过可听频率的20～50kHz范围的频率下点灯,其发光效率比在
1 fluorescent lamp inverter used in what kind of inverter technology has been widely spread to the field of home appliances, its name is also well-known. It is usually used in the field of variable frequency and other controllability as a feature to use more often, but lighting inverter, especially the inverter used in fluorescent lamps have another obvious feature. Fluorescent lamps are converters that convert electrical input into light output. By lighting at high frequency, the conversion efficiency can be greatly improved. This has become an important feature of lighting inverters. For example, lighting a fluorescent lamp at a frequency in the range of 20-50 kHz above audible frequency has a luminous efficiency of
