converters have recently been started to be used frequently in power
electronics applications in parallel with the development of semiconductor
technology. </span> <span lang="en-us" style="font-size:12pt;line-height:150%;font-family:’Times New Roman’, serif;" xml:lang="en-us"> </span> <span lang="en-us" style="font-size:12pt;line-height:150%;font-family:’Times New Roman’, serif;" xml:lang="en-us">It is possible to encounter frequently to these converters, which are
basically divided into two groups as DC choppers and switching regulators, in
transport vehicles, chargers and physically small electronic devices. Also,
choppers are one of the effective methods used to control of DC motor. In this paper,
a detailed analysis of DC choppers, a type of DC-DC converters, has been
performed. </span> <span lang="en-us" style="font-size:12pt;line-height:150%;font-family:’Times New Roman’, serif;" xml:lang="en-us"> </span> <span lang="en-us" style="font-size:12pt;line-height:150%;font-family:’Times New Roman’, serif;" xml:lang="en-us">Firstly, DC choppers operating in the 1 <sup>st </sup>, 2 <sup>nd </sup>, 3 <sup>rd </sup>
and 4 <sup>th </sup> quadrants have been designed separately. </span> <span lang="en-us" style="font-size:12pt;line-height:150%;font-family:’Times New Roman’, serif;" xml:lang="en-us"> </span> <span lang="en-us" style="font-size:12pt;line-height:150%;font-family:’Times New Roman’, serif;" xml:lang="en-us">Secondly, </span> <span style="font-size:12pt;line-height:150%;font-family:’Times New Roman’, serif;">
a </span> <span lang="en-us" style="font-size:12pt;line-height:150%;font-family:’Times New Roman’, serif;" xml:lang="en-us"> converter model operating in
both the 1 <sup>st </sup> quadrant and the 3 <sup>nd </sup> quadrant has been
designed by combining the 1 <sup>st </sup> and 3 <sup>rd </sup> quadrant converters
due to the fact that two-quadrants or four-quadrants control can be performed
by combining the quadrants. Finally, all of the simulation models have been
designed in the Matlab/SIMULINK environment and the current and voltage
components of the converters have been measured. </span> <span lang="en-us" style="font-size:12pt;line-height:150%;font-family:’Times New Roman’, serif;" xml:lang="en-us"> </span> <span lang="en-us" style="font-size:12pt;line-height:150%;font-family:’Times New Roman’, serif;" xml:lang="en-us">Furthermore, an example of DC motor speed control with
a chopper having one quadrant have been given as an example to the application
areas of the choppers. </span> <span lang="en-us" style="font-size:12pt;line-height:150%;font-family:’Times New Roman’, serif;" xml:lang="en-us"> </span> <span lang="en-us" style="font-size:12pt;line-height:150%;font-family:’Times New Roman’, serif;" xml:lang="en-us">Consequently, it has been observed that the
performance of the chopper fed control techniques is also quite high compared
with the DC motor control techniques in the literature. </span> <span style="font-size:12pt;line-height:150%;font-family:’Times New Roman’, serif;"> </span> </p> <p> </p>}, number={1}, publisher={Ağrı İbrahim Çeçen University}
