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. As power semiconductor devices are the key components of hybrid DC circuit breakers (HCBs), how to select suitable devices is critical for the whole HCB de.

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. IGCT are available with or without reverse blocking capability.
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.
Integrated gate-commutated thyristor Type Passive First production ABB Mitsubishi Pin configuration anodegate and cathode Electronic symbol The integrated gate-commutated thyristor IGCT is a power semiconductor electronic device, used for switching electric current in industrial equipment. This results in a complete elimination of minority carrier injection from the lower PN junction and faster turn-off times. The drive circuit PCB is integrated into the package of the device.

Asymmetrical IGCTs can be fabricated with a reverse conducting diode in the same package. An IGCT is a special type of thyristor.
Views Read Edit View history. Gate drive electronics are integrated with the thyristor device. The main applications are in variable- frequency invertersdrives and traction.
Multiple IGCTs can be connected in series or in parallel ihct higher power applications. The wafer device is similar to a gate turn-off thyristor GTO. They typically have a reverse breakdown rating in the tens of volts.
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.

The close integration of the gate unit with iyct wafer device ensures fast commutation of the conduction current from the cathode to the gate. The drive circuit surrounds the device and a large circular conductor attaching to the edge of the IGCT is used. The large contact area and short distance reduce both the inductance and resistance of the connection.
Reverse blocking capability adds to the forward voltage drop because of the need to have a long, low-doped P1 region.
