If you select the desired model and click here, the zip file with the following name will be downloaded.įor PSpice model: (product name)_PSpice_(registration date).zipįor LTspice models: (product name)_LTspice_(registration date).zip Used in high voltage / current & high frequency switching power applications (Inverters, SMPS).G0 and G2 models can be downloaded from above linkage destination.Used in high speed power converters like inverters & choppers.PT normally operated as a switch in CE config.Used in heat / light control, ac motor control circuit.Įxample of Inverter Grade Thyristor Ratings Ex: Converter grade (line commutated) SCR.Line Commutated Thyristors available up to 6000V, 4500A.Madhusudhan Rao, E&C Dept., MSRITĬomparison between different commonly used Thyristors Power Semiconductor Devices, their Symbols & Characteristics 14ĭEVICE SYMBOLS & CHARACTERISTICS 15 Prof. GATT = Gate Assisted Turn Off Thyristor.N-Channel MOSFET = N-Channel Metal Oxide Silicon Field Effect Transistor.IGBT = Insulated Gate Bipolar Junction Transistor.NPN BJT = NPN Bipolar Junction Transistor.IGCT = Insulated Gate Controlled Thyristor.( Switching speed lower than MOSFET) 10 Prof. Higher current capability & higher switching speed than a BJT.Low on state conduction power loss like BJT.Simple gate drive, Lower switching loss.Combines the advantages of BJT & MOSFET.Semiconductor Cross-section of IGBT 8 Prof. Gate pulse width critical for turn-off for larger currents.Gate pulse width not critical for smaller device currents.Gate controlled possible if current is less than peak controllable current. High switching speeds achieved due to fast turn-on & turn-off.Low on-state losses & large current capabilities.One MOSFET for turning ON the MCT and the other to turn OFF the MCT.
Basically a thyristor with two MOSFETs built in the gate structure.New device that has become commercially available.Jawale Head and Associate Professor Department of Electronics Yeshwantrao Chavan Mahavidyalaya, Tuljapur B.Sc.-I Sem-I Paper-I 1
