Tuag -Lub Sijhawm Tswjhwm
Hauv ib nrab-bridge/full-bridge topologies, lub sij hawm tuag (feem ntau 0.5 ~ 2μs) yuav tsum tau muab tso rau thaum lub sij hawm hloov ntawm sab sauv thiab qis transistors los tiv thaiv luv luv Circuit Court. Cov neeg tsav tsheb niaj hnub no tuaj yeem tso rau lub sijhawm no.
Freewheeling Diode kev koom tes
IGBT yog ib qho khoom siv unidirectional. Inductive loads (xws li motors lossis transformers) yuav tsum muaj ceev rov qab diodes (FWD) txuas rau tib lub sijhawm los muab txoj hauv kev rov qab tam sim no.
Hom Kev Xaiv
Saturating Type (PT-IGBT): Tsim nyog rau DC circuits (xws li DC-DC converters) uas tsis tshua muaj hluav taws xob rov qab muaj peev xwm.
Tsis yog -Saturating Type (NPT-IGBT): Haum rau AC lossis bidirectional voltage scenarios (xws li inverters) nrog symmetrical blocking peev xwm.
