As you see in the above circuit diagram of electronic ballast first a series resistor is connected. It refers to that part of the circuit which limits the flow of current through the lighting device and may vary from being a single resistor to a bigger complex device. The rectified DC is applied to this stage which immediately starts oscillating at the required.

Use of this pulsed DC voltage overcomes many of the above described disadvantages of earlier circuits but creates other problems especially where two transistors are configured in a push-pull. The next comprises a simple two transistor cross-coupled oscillator stage. In some electronic ballast a fuse is used instead of a series resistor.

Electronic ballast is a device which controls the starting voltage and the operating currents of lighting devices. 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. Certain electronic ballast circuits have been designed with the electrolytic capacitor omitted and with the circuit driven by the resultant full wave rectified signal generated from the AC source.

Basic Circuitry of an Electronic Ballast In present days electronic ballast design is so robust and somewhat complicated to work very smoothly with high leveled controlling ability.

Another type of ballast resistor which corresponds to this is an inductive ballast. The AC signal is first rectified and filtered using a bridgecapacitor configuration. The basic components used in the Electronic Ballast are listed below.

INTRODUCTION Fluorescent lamps have applications in most areas of lighting where they give longer lifetime and lower power consumption for equivalent light output compared to filament bulbs with the disadvantage of higher initial cost. The RFI and EMI filters in the figure filter out conducted RF interference and electromagnetic interference from the grid while obstructing the conducted RF and. HALF BRIDGE CIRCUIT DESIGN 3.

The advantages of such a ballast are. It is connected to limit the overload and short circuit current. Annonce Le Site n1 sur lHydroponie et le Matériel de Culture Indoor.
