Soft Starter

Soft-Starter é um dispositivo electrónico composto de pontes por tiristores (SCRs na configuração antiparalelo) accionadas por uma placa electrónica, a fim de controlar a tensão de partida de motores de corrente alternada trifásicos. O seu uso é comum em bombas centrífugas, ventiladores e motores de elevada potência cuja aplicação não exija a variação de velocidade.

O soft-starter controla a tensão sobre o motor através do circuito de potência , constituído por seis SCRs, variando o ângulo de disparo dos mesmos e consequentemente variando a tensão eficaz aplicada ao motor. Assim, pode-se controlar a corrente de partida do motor, proporcionando uma "partida suave" (soft start em inglês), de forma a não provocar quedas de tensão eléctrica bruscas na rede de alimentação, como ocorre em partidas directas.

Costumam usar a tecnologia chamada by-pass, a qual, após o motor partir e receber toda a tensão da rede, se liga um contator que substitui os módulos de tiristores, evitando sobreaquecimento dos mesmos.
