GTO working vi characteristics These gate turn-off thyristors are useful in a number of areas, particularly within variable speed motor drives, high power, inverters and similar areas. The turn-off for the GTO is accomplished by the application of a large Thyristor includes many types of switches, some of them are SCR (Silicon Controlled Rectifier), GTO (Gate Turn OFF), and IGBT (Insulated Gate Controlled Bipolar Transistor) etc. If positive pulse applied between the cathode and gate terminals, then the device will be turned ON. The GTO is turned on in the same manner as the thyristor structures described early. • The 3 terminals of a thyristor is known as Anode, Cathode and Gate. 6. It is similar to the gate turn-off (GTO) thyristor, but much less drive power is needed to turn off the MCT because little current flows into the gate.

Gate Turn-off Thyristors. Thyristors, Static V-I Characteristics of SCR, TRIAC, GTO & IGBT, Turn-On & Turn-OFF Mechanism of SCR, Gate Turnoff Thyristor (GTO) .Power BJTs . Turned off by applying negative gate signal. Power MOSFETs - Insulated Gate Bipolar Transistors (IGBTs) - Basic Structure and VI Characteristics. be designed to turn on and turn off the current flow under control by a gate signalin a DC circuit was motivated by this need. Types of Thyristors • There are four major types of thyristors: Silicon Controlled Rectifier Gate Turn-off Thyristor (GTO) &Integrated Gate Commutated Thyristor (IGCT) MOS Controlled Thyristor (MCT) Static Induction type Thyristor 7. Thyristor Summary • • • A thyristor is a latching device and it can be turned on with a small gate pulse, typically 100μs . Simply, SCR is a kind of Thyristor. 12. GTO Symbol. Turned on by applying positive gate signal. gate metallization J 3 J 2 J anode 1 cathode gate GTO (Gate Turn-off Thyristor) Construction GTO circuit symbol • Unique features of the GTO. Static, dynamic and thermal characteristics. 5 THYRISTOR APPLICATIONS INFORMATION Gate control will be normally lost once switching occurs . But SCR is the most widely used device, so the word Thyristor become synonymous to SCR. Such thyristors have been named gate turn-off (GTO) thyristors. Tegangan keadaan on dari thyristor 2200 A, 1800 V, dan waktu turn off sangat cepat, sekitar 3 sampai 5 µs, biasa dikenal sebagai asymmetrical thyristor (ASCRT). Protection, cooling and mounting techniques. GTO Turn-on and Turn-off Pulses 53. The gate terminal controls the switches to be turned ON and OFF. 13 13 14 Advantages over SCRs. Thyristors are generally off by line commutation due to the natural behavior of the input ac line supply. Gate turn off Thyristors (GTOs) One of the special types of high power semiconductor devices is GTO (gate turn-off thyristor). Gate Turn-Off Thyristors - Free download as Powerpoint Presentation (.ppt), PDF File (.pdf), Text File (.txt) or view presentation slides online. GTOs Schematic representation 52. GATE-TURN-OFF THYRISTOR (GTO) Gerbang ini dapat dihidupkan dengan memberikan sinyal gerbang positif dan dapat dimatikan dengan memberikan gerbang sinyal negative. The Gate Turn-Off Thyristor (GTO) 51. • It is a bistable device. Controllable peak on-state current ITGQ is the peak value of on-state current which can be turned-off by gate control.
