Reduced Voltage Start Soft Starter

Reduced Voltage Start. Reduced voltage starter systems are soft starts that often use autotransformers to adjust the voltage during starting. Once the motor gets up to full speed, the autotransformer will then be switched out, and the motor will be able to run at full voltage.

work an attempt is made to develop a soft starter for a three phase Induction Motor drive. The soft starter uses two anti parallel connected switches in each phase. The IGBT‟s are used as the switches in this work because of their higher power rating and high efficiency. The Fig. 1 shows the block diagram of the entire system. In the Fig.1 the motor is connected to the soft starter at the

The ABB autotransformer starter is a closed transition type, meaning that the motor remains connected to the line during the entire acceleration period. The transformer has three taps which provide 50%, 65% and 80% of full line voltage. At delivery, the transformer is connected to the 65% tap; the inrush current will be reduced to 42% of normal; and the starting torque will be reduced to 42%
