The thesis reveals an aspect of DC/DC converter, which is four-quadrant pulse converter control for DC motor and simulation the system based on the environment of Matlab Simulink software. The thesis studies contain the introduction of structure, operation and different types of DC converter control for the DC drive machine. Moreover, depending on the theoretical part simulate the drive system and appraise its features for different types of control. The final is the ability to improve the simulation system.The thesis reveals an aspect of DC/DC converter, which is four-quadrant pulse converter control for DC motor and simulation the system based on the environment of Matlab Simulink software.
