IGCT VS IGBT PDF
The integrated gate-commutated thyristor (IGCT) is a power semiconductor electronic device, used for switching electric current in industrial equipment. It is related to the gate turn-off (GTO) thyristor. It was jointly developed by Mitsubishi and ABB. Comparison of IGCT and IGBT for the use in the. Modular Multilevel Converter for HVDC applications. Martin Buschendorf, Jens Weber, Steffen Bernet.

Integrated gate-commutated thyristor
IGCT are available with or without reverse blocking capability. Usually, the reverse blocking voltage ibgt and forward blocking voltage rating are the same.

It was jointly developed by Mitsubishi and ABB.

The large contact area and short distance reduce both the inductance and resistance of the connection.

A-IGCTs are used where either a reverse conducting diode is applied in parallel for example, in voltage source inverters or where reverse voltage would never occur for example, in switching power supplies or DC traction choppers. This results in a complete elimination of minority carrier injection from the lower PN junction and faster turn-off times.

Views Read Edit View history. The main differences are a reduction in cell size, and a much more substantial gate connection with much lower inductance in the gate drive circuit and igcr circuit connection.
Gate drive electronics are integrated with the thyristor device. The IGCT’s much faster turn-off times compared to the GTO’s allows it to operate at higher frequencies—up to several kHz for very short periods of time. The drive circuit surrounds the device and a large circular ve attaching fs the edge of the IGCT is used. An IGCT is a special type of thyristor.
They typically have a reverse breakdown rating in the tens of volts.
The main applications are in variable- frequency invertersdrives and traction. Reverse blocking capability adds to the forward voltage drop because of the need to have a long, low-doped P1 region.
Asymmetrical IGCTs can be fabricated iggct a reverse conducting diode in the same package. The close integration of the gate unit with the wafer device ensures fast commutation of the conduction current from the cathode to the gate.
The typical application for symmetrical IGCTs is in current source inverters. The wafer device is similar to a gate turn-off thyristor GTO.
