What is the capacity of the capacitance in the electronic ballast?
According to the size and design factors of power, the power small capacity is generally small and the power capacity is large. Electronic ballast, a kind of ballast, refers to Electronic devices that use Electronic technology to drive electric light sources to produce the needed lighting. Corresponding to this is the inductor type ballast (or ballast). Modern increasingly use electronic ballast fluorescent lamp, portable small, even can integrate electronic ballast and tube together, at the same time, the electronic ballast can usually combine functions, the starter and starter can save separate again. Electronic ballasts can also have more functions, such as by improving the current frequency or current waveform (e.g., into a square wave) to improve or eliminate fluorescent lamp flickering phenomenon; It can also be used to make fluorescent lamps use dc power. Some of the shortcomings of the traditional inductive rectifier have been replaced by an increasingly sophisticated electronic ballast.
According to the size and design factors of power, the power small capacity is generally small and the power capacity is large. Such as is common in the market to 11 w energy-saving lamp ballast with p (2 n2) of more than 2200, more than 20 watts in 3200 p (n2), 40 tile are 10000 p (n) 10, according to the product design experiments to decide, different manufacturers also have minor deviations, but according to the principle to select. Start capacitor start instantaneous voltage is higher, generally choose 630 v and above pressure, lowest cost CL11 capacitance, breakdown is higher also, but can choose CBB13 capacitance, a bit better, other metallized capacitors Do start is also very good, but cost much higher.
According to the voltage of the lamp and the state guarantee of the normal working condition, the non-capacitive mode is not the same as the IC waveform of the triode
