Great Ballast Circuit Diagram
This auto regulator ballast is most popular and it is intended as trade off.
Ballast circuit diagram. Such type of rectifier is simply not advised for anything at all apart from an assessment circuit or reduced power compact fluorescent and without a doubt could become. Considering that the input rectifiers carry out just close to the peaks of the ac input voltage the input power factor is around 0 6 lagging with a non sinusoidal current wave form. This compact lightweight high frequency electronic ballast is designed to operate off the 230v ac mains supply at 50 60 hz and is suitable for 36 40 w fluorescent tubes the advantages of such a ballast are.
In some electronic ballast a fuse is used instead of a series resistor. Standard ballast circuit for fluorescent tube l tube t mains 220 v 50 hz c s bi metallic trigger the operation of a fluorescent tube requires several components around the tube as shown in figure 3. Otherwise the structure won t function as it ought to be.
The gas mixture enclosed in the tube is ionized by means of a high. It has bad regulation property. Voltage fed half bridge quasi resonant lamp ballast startup circuit shown shaded grey figure 3.
1 electronic ballast block diagram. It causes a variation in. The auto regulator ballast has the features of both the lag ballasts and the regulator ballasts.
With some 3 and 4 lamp programmed start ballasts wired in series parallel if a single lamp in one branch fails the lamp s in the parallel branch. Each component ought to be placed and connected with different parts in particular manner. As you see in the above circuit diagram of electronic ballast first a series resistor is connected.
Figure 3 gives the typical electrical schematic diagram for the standard line operated fluorescent tube control. When an instant start ballast wired in parallel operates multiple lamps in a circuit the lamps operate independently of each other. Control circuits the half bridge resonant output stage is necessary for each ballast topology and is controlled with a voltage controlled oscillator vco input and a high and low side half bridge driver output figure 2.
