Medium Voltage Softstarter

Reliable solutions for asynchronous and synchronous machines for industrial applications

Ansaldo Sistemi Industriali  can also provide Medium Voltage Softstarters to start asynchronous motors in any fixed speed. Our softstarters ensure smooth, step-less control of acceleration.
The softstarters are designed to eliminate mechanical shocks and reduce inrush current to protect both motor and load. Our medium voltage softstarter provides a high level of safety and power quality immunity with high level isolation circuit via optical fibres.

To start a large synchronous machine with no noise on the network, Ansaldo Sistemi Industriali provides its LCI topology - Silcovert S, load-commutated current source inverter for synchronous motors.
In this situation, the Silcovert S provides high availability. The softstart of the motor reduces the stress on the line and guarantees longer equipment lifetime.
As a starter, Silcovert S is commonly used on turbogas pumping station units using large synchronous machines. In these cases, the Electric Generator acts as the gas turbine starter.
