Abstract
In Our Project we first convert Ac to Dc, to equalize the current in to Dc and then
convert Dc in to Ac to get pure sinusoidal wave with variable frequencies of 50 -
60 Hz. The solar inverter is a critical component in a solar energy system. It
performs the conversion of the variable DC output of the Photovoltaic (PV)
module(s) into a clean sinusoidal 50 or 60 Hz AC current that is then applied
directly to the commercial electrical grid. Now By describing our Scope we come
to know that how it's make.
The ever-increasing reliance on electronic devices which utilize AC power
highlights the problems associated with the unexpected loss of power from the
electrical grid. In places where the electrical infrastructure is not well-developed,
brown-outs can prove fatal when electronic medical instruments become unusable.
Therefore, there is a need for inexpensive and reliable pure-sine wave inverters for
use with medical devices in the underdeveloped world. This report documents the
development of one component of an uninterruptible power supply, the DC-to-AC
inverter. Through the use of analog signal processing techniques, a prototype
which efficiently and accurately emulates the pure-sine wave power present on the
power grid was created. The three-level PWM system within this report is created
with the possibility of a feedback-regulated system to be implemented in the
future.
