摘要

Aiming at the starting problem of motor equipment, this paper studied a large of existing soft start modes and their starting characteristics. Then, using MATLAB/Simulink tool to build common soft start simulation models, this paper got a lot of simulation waveforms. These helped to identify the applicable occasions of these soft starters and their respective advantages and disadvantages. We designed an integrated soft starter that includes voltage ramp soft start, current limit soft start, voltage jump soft start, and discrete frequency soft start based on dsPIC6014a in the premise of doing these efforts, and given the system's hardware and software design in detail. The test results on the experimental platform showed that this design can easily set the start modes according to different starting requirements and all the modes possess so prefect control effect that motor can start smoothly, and experimental data indicators also meet operation requirements. So it is worthy of promotion and application.
