SMART ELECTRONIC LIGHTING BALLAST APPLICATION FOR SALTWATER ENVIRONMENT

This work is about the design methodology of electronic ballast for saltwater
environment application. The effect of environment to electronic devices research
stated that electronic circuit exposed to salty environment has high tendency to
damage. Therefore, the protection scheme needs to be added to avoid malfunction.
The power supply cut-off circuit is the simplest way to protect ballast from damage
at the input terminal. All the circuit simulation is performed using NI Multisim
circuit simulator. It is found that self oscillating electronic ballast with power supply
cut off circuit is the simplest way to protect ballast circuit at saltwater application. By
stages, an electronic ballast circuit is simulated and the output waveform is observed.
Start with bridge rectifier, which is produce smooth DC voltage. Then follow by
basic ballast circuit. Next, the circuit improved using self oscillating driver. Lastly,
electronic ballast circuit combined with power supply circuit.
