Simulation and modelling of input for AC to DC inverter / Muhallimah Ardianto and Siti Rohani Kasim

The advancement of technology has given many benefits to human being and universe as a whole. We can see obviously the changes in the engineering and medical field. The evolution of electrical engineering knowledge has give create many changes to the world. The creation of transistor in the middle of 20th century by three scientists has a very big impact to the revolution of computer, communication and digital.
In our project, we were responsible to make something that can supply voltage to the inverter. There are so many sources that have been selected to us, such as wind, water, car battery, solar panel, generator and etc. As a successful engineer, we need to create the circuit ourselves. This is due to a few reasons. First, we consider on the cost. Second, we think about the difficulties and their ability in some cases that may be happen soon. So, we have made up our mind to create the circuit that function almost the same as adaptor. Although it is quite simple and less cost, we also can achieve our main target.
We are responsible to supply 12VDC to the inverter. As a summary, our circuit will reduce the 230VAC from the main source and step down to 12VDC before supply to the inverter
