Electronic Ballasts
Dimmable electronic ballast
Fluorescent lamps are controlled by an electronic ballast that provides the necessary ignition voltage for the discharge that provides the illumination. Since a minimum voltage must be provided for the ignition to start, providing a means for dimming the voltage is difficult, as simply varying the supply voltage (which would be effective with say a conventional filament light bulb) cannot be used without jeopardising the ignition voltage.
Notwithstanding this difficulty providing a dimmable ballast is desirable for a number of reasons, including the desire of energy efficiency, and the desire to create a pleasant working environment. A range of techniques have been developed to enable a dimmable fluorescent lamp to be created. For example dimming may be provided by controlling the switching frequency so that the impedance of the limiting inductor in the ballast can be varied so as to control the current into the lamp. Another way of providing dimming control is to control the duty-cycle of the switching devices (switching at constant frequency) so that the average applied voltage and current in the lamp can be varied.
Moreover, of particular importance in the design of electronic ballasts are the requirements for high power factor, low total harmonic distortion, low electromagnetic interference (EMI), low lamp current crest factor, and low flickering. In order to comply with the requirements of certain international standard (for example IEC1000-3-2 Class C appliances), commercially available products usually consist of two cascaded stages for the input power factor correction (PFC) and output high-frequency inversion. A regulated dc voltage, for example 400V, inter-links the two stages. Some specialized integrated circuits have been developed for this particular application to simplify the circuit schematics. For the input stage, boost- and flyback-type pre-regulators are the most popular choices. For the output stage, either a voltage-fed or current-fed inverter is usually chosen. A resonant tank circuit is used because of its distinct advantages of near-sinusoidal lamp current and high voltage generation during the ignition period. The dimming operation is based on adjusting the switching frequency of the inverter so that the reactance of the series inductor can be varied and thus the lamp power can be controlled.
In order to simplify the overall circuitry and reduce the manufacturing cost, many passive PFC circuits and single-stage electronic ballast with dimming features have recently been reported. Some of them minimize the circuit structure by integrating the switch in the PFC into one of the switches in the inverter. However, their structural elegance is offset by various problems, such as high lamp current crest factor, asymmetrical lamp voltage and current waveforms, high dc link voltage at low luminous level, high component stresses, and narrow dimming range. In order to achieve a desired dimming range and soft-switching of the switches in the inverter, the switching frequency of the inverter has to be varied in a single-stage system. This can result in lamp current and voltage waveform distortion. The dc link voltage has to be set to a much higher value, which can be two to three times higher than the rated value of the supply voltage for reducing the above problem. This aspect is particularly problematic for countries having high-voltage mains supply, such as 220V in Hong Kong and the UK, resulting in the requirement for a very high voltage dc link capacitor for stabilizing the inverter input.
Furthermore, existing dimmable ballasts are generally four-wire systems--two (conventional live and neutral) for the ac supply mains input and the other two connecting to a variable dc voltage input (for example 0-10V) or variable resistor for dimming control. Recently, a ballast that can provide a dimming features using a TRIAC-based dimmer at the supply mains has been proposed in "Phase-controlled dimmable electronic ballast for fluorescent lamps" of W. Ki, J. Shi, E. Yau, P. Mok, and J. Sin, in Proc. IEEE Power Electron Spec. conf. 1999 pp1121-1124. However, the dimmer has to be modified so that the actual firing angle is varied within few degrees of angle only. It has been proposed in "TRIAC dimmable integrated compact fluorescent lamp" of J.Janczak in J. of Illuminating Eng. Soc., pp144-151 1998 to use an ordinary dimmer to adjust the luminous level of compact fluorescent lamps. The dc link voltage is kept at a relatively constant value throughout the dimming range.Again, changing the switching frequency of the inverter varies the outputluminous level, and the dimming range is relatively narrow.
An electronic ballast which is able to provide effective dimming control of a fluorescent lube (either of tubular or compact type) is provided by the described circuits. A circuit which is able to provide a substantially transformed dimming control over a particularly wide range is provided. It is found that this linearised circuit reduces the flickering and dark ring effects in the low dimming and low power regions of operation, which is advantageous for the lifetime of a fluorescent lamp.

How difficult is it to replace an electronic ballast in a kitchen light fixture?
I have a strange electrical problem. Our kitchen light went out, and after several weeks, suddenly came back on. It remained functional for several weeks, then went back out again. During this time it would intermittently go out for several minutes, and come back on. Both of the bulbs were very dark so we replaced them, to no avail. Everyone we spoke to advised us to buy a new fixture, as the ballast would be more expensive to replace. Oddly enough, I ordered a new, electronic ballast from the manufacturer (Sunpark Electronics) for $6.50. The fixture sells at Home Depot for $85. Can anyone tell me if they think a new ballast will resolve the problem? I'm also curious to know why the electricians & diy'ers were so certain the ballast would cost more than a new fixture. Admittedly, I haven't tested anything as I am respectful of something I know very little about, and quite frankly...it scares me! Thanks in advance.
you have a simple fix, turn the light off, read the directions and wiring diagram on the ballast, they are easy to replace, you may need some small wirenuts as you will have to cut the wire going to the sockets so you can splice the new ballast in, Electronic ballast DO NOT have starters so no need to look for one...Hope this helps
