WebThe paper considers the issues of effective direct start of high-voltage asynchronous motors of high power with the help of “thyristor voltage regulator - asynchronous motor” (TVR-AM) system. To increase the voltage and power of TVR in the work it is proposed to use series-parallel connected groups of thyristors (TG) instead of one thyristor TVR. WebSoft start is the gradual turning on of an electronic power supply to avoid stressing the components by the sudden current or voltage surges associated with the initial charging of capacitors and transformers. The soft start function in a power supply circuit minimizes large startup currents from flowing when the input power is first applied.

WebSoft starters are also semiconductor devices used to start or stop a motor. As the name indicates it offers a smooth start and smooth stop. Usually, soft starters are bypassed by a contactor-overload circuit as the motor gradually reaches its full speed and gets back into action when the motor stops.
