Integrated gate-commutated thyristors (IGCTs) consist of a thyristor and diode integrated into the same package. They are a specialised type of side-gate triggered thyristor, usually with a higher gate-trigger current compared to most thyristors and are designed to be used in switchmode power supplies. The CM450DX-24S is an example of an IGCT module. It has many of the same features as a thyristor, but with some important differences, making it a better choice for high-power applications.

In terms of its application field, the CM450DX-24S finds its most useful application in medium and high voltage power transmission and distribution systems. It can be used as a switch to control the widely-used three-phase AC line. It is often used to control the magnitude of alternating current over a significant distance, as it can handle higher currents and voltages with greater efficiency than other similar components. Additionally, it can be used in inverter applications as it is able to handle power fluctuations and has a fast switching speed.

The working principle of the CM450DX-24S is based on the use of power semiconductor devices, namely thyristors and IGBTs, in order to control current. It is designed to be used in circuit switching and power control applications. The principle of operation of the module is based on the commutation of a transistor with its self-commutation or turn-off process. This IGCT ranges in voltage ratings from 200 to 2480V, and a maximum current of 450A up to 1100A depending on its configuration. Its control input is single-phase AC and its output contains three phases; for its operation it requires one thyristor for each phase.

The CM450DX-24S IGCT module is an important technological advancement in terms of power control. Its commutation methods and its ability to handle power fluctuations make it useful in many medium and high voltage applications, from the transmission and distribution of electricity over a significant distance to the operation of inverters. The thyristor and IGBTs embedded in its design enable it to handle higher currents and voltages with greater efficiency. It is a crucial component in power control and its increasingly common use is a testament to this fact.
