| Summary: | With the recurrent oil crises and the new environmental boundary conditions
for energy production and use, the Photovoltaic, PV, system development can be a
very promising strategic solution, which realises together with the Photovoltaic
energy cost effectiveness goal, an actual clean, renewable, and alternative energy
option. However, the continuos decline in Photovoltaic module prices in the
international market gives more attention to design the supplementary equipment with
low cost and high reliability, such as DC-to-AC inverter
For that reason, this project has the objective of designing and implementing a
prototype DC-to-AC invel1er which used to power small houses or huts in the rural
areas. The input of this inverter is four batteries of twelve volt, which would be
charged by a photovoltaic solar array. The design of the solar array and its controller
is not within the aim of this project. However, a theoretical study is given for the
photo voltaic system in the first chapters for a purpose of illustration.The DC-to-AC invel1er is designed as a single phase bridge switched mode
circuit, using power MOS FET switches and electronic components that are common
and with low cost. For the sake of simplicity, a single pulse width modulation is
applied which gives a reasonable efficiency with rejection of the third harmonic and its
multiple. The detailed analysis of the design and experimental construction of the
inverter are discussed in this report. |
