From Wikipedia, the free encyclopedia. This results in a complete elimination of minority carrier injection from the lower PN junction and faster turn-off times. They typically have a reverse breakdown rating in the tens of volts.

The drive circuit surrounds the device and a large circular conductor attaching to the edge of the IGCT is used. IGCT are available with or without reverse blocking capability. Asymmetrical IGCTs can be fabricated with a reverse conducting diode in the same package.

Usually, the reverse blocking voltage rating and forward blocking voltage igtb are the same. Multiple IGCTs can be connected in series or in parallel for higher power applications. In an IGCT, the gate turn-off current is greater than the anode current.

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. This page was last edited on 22 Novemberat Views Read Edit View history.

It was jointly developed by Mitsubishi and ABB. The typical application for symmetrical IGCTs is in current source inverters. The main applications are in variable- frequency invertersdrives and traction. The drive circuit PCB is integrated into the package of the device. 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 drive circuit connection.

Retrieved from ” https: An IGCT is a special type of thyristor. Jgct wafer device is similar to a gate turn-off thyristor GTO. The integrated gate-commutated thyristor IGCT is a power semiconductor electronic device, used for switching electric current in industrial equipment.

Integrated gate-commutated thyristor

Reverse blocking capability adds to the forward voltage drop because of the need to have a long, low-doped P1 region.

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

The close integration of the gate unit with the wafer device ensures fast commutation of the conduction current from the cathode to the gate.
