The whole arrangement of the inverter is shown below with the input dc voltage of 48Volt from the lab module.

₪PRACTICAL IMPLEMENTATION(CONTINUE) ₪

₪ ADVANTAGES OF THE PROJECT ₪

System cost is the most effective one. The system consumes low energy. Can work in very harsh environment.

o Very effective for car parking system.o Traffic control system.o Frequency changes tells the type of

vehicle.

₪ FUTURE WORK ₪

We expect that this project will carry a great motive regarding the utilization of the Induction Loop vehicle counter in our country.
