Qhov zoo tshaj plaws anti-parallel thyristor Cheebtsam thiab cov khoom siv hluav taws xob tswj kev sib txuas ntawm stator winding ntawm lub siab voltage lub cev muaj zog thiab cov khoom siv hluav taws xob. High voltage soft start state txee tuaj yeem siv dav hauv steel, tshuaj, metallurgy, tsev cov ntaub ntawv, thee thiab lwm yam kev lag luam.
