Here are the various ways to start soft-start of AC motors, from the earliest mechanical start-up methods to electronic thyristor soft-starts and frequency converters, and outline the advantages and disadvantages of these start-up methods. The key point is to introduce the intelligent and operability of thyristor soft start and inverter start mode. Through more detailed comparison, it is concluded that the inverter is not suitable for general soft starter, and the thyristor soft starter is the best for the current conventional motor.
