Because of its good speed regulation performance and control performance, DC motor is still widely used in many fields. Currently, in the field of the DC Speed regulation, the pulse width modulation speed control technology is developing rapidly, and has very broad application prospects. In this paper, PWM DC Speed Regulating System Design are researched and discussed, including designs of PWM power conversion circuit, control circuit, protection circuit and other circuits of the system, and the corresponding parameter calculation and component selection. At last designs were verified with simulation software. |
