摘要
In the article, a refined model of a gatecontrolled thyristor is considered for Matlab 7.0. The introduced model, unlike the one presented in Simulink library, takes into account presence of the thyristor recovered charge. By the example of a six-pulse controlled rectifier model, influence of the recovered charge on the magnitude of repetitive voltage surge on the thyristor is shown. A repetitive overvoltage protection circuit calculation algorithm is given.
