The process of starting a three-phase induction motor consumes a very largecurrent from the power grid, which can cause voltage drops and damage the coilinsulators due to the heat generated. However, this has been overcome by using severalstarting methods including star-delta starter, starter with autotransformer, soft starter,and drive frequency or better known as VFD or VSD. In conventional soft starters, asmall reduction in voltage results in a sizable drop in electromagnetic torque. This cancause a motor with a certain load to fail to start. In this research, a three-phase inductionmotor soft starter modeling will be carried out using the method of setting the sourcevoltage and frequency, designed to overcome the low electromagnetic torque generatedby conventional soft starters. The modeling of the soft starter with thyristor control isexpected to produce high and stable electromagnetic torque. So that the soft starter withthyristor control can be a solution for conventional soft starters.
