Detailed Analysis of DC Choppers and An Example of PMDC Motor Speed Control

Detailed Analysis of DC Choppers and An Example of PMDC Motor Speed Control

DC-DC converters have recently been started to be used frequently in power electronics applications in parallel with the development of semiconductor technology. 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. Firstly, DC choppers operating in the 1st, 2nd, 3rd and 4th quadrants have been designed separately. Secondly, a converter model operating in both the 1st quadrant and the 3nd quadrant has been designed by combining the 1st and 3rd 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. 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. 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.
