IXGK120N120A3 Application Field And Working Principle

The IXGK120N120A3 is part of IXYS\'s IXGK IGBT series, specifically a 600V IGBT module. It was originally designed for use in the Industrial, Mining, Utilities and Air Conditioning industries. This module can handle a maximum current of 120A, power dissipation of 6W per module, and a maximum junction temperature of 175°C. The device is also equipped with an active Integrated Intelligence (II) control system to better manage its device performance, while also providing robust protection against various fault conditions.With its sophisticated capability, the IXGK120N120A3 is suited for use as a switching device in applications such as motor drives, AC/DC converters, solar inverters, UPS, frequency changers, and PWM inverters.

IGBTs are essentially a combination of a BJT and a MOSFET, combining the benefits of both devices. Through the combination of their respective components, they contain lower on-state voltage drop, faster switching speeds, larger current handling capabilities, and better noise immunity. This makes them extremely popular as a power switch for AC and high frequency DC motor control.

The IXGK120N120A3 is a single IGBT integrated module with a 600V rating, capable of operating at a maximum current of 120A. The device is also equipped with an active II control system that allows for easy monitoring and control of its performance by providing robust protection against various fault conditions. Additionally, the module offers a wide range of features such as wide voltage range, low power losses, high switching speed, and high thermal stability.

The IXGK120N120A3’s working principle is relatively simple. When an external voltage is applied, the gate-emitter junction in the device will enter into a conductive path, allowing electric current to flow. The current will then flow through the collector-emitter junction of the IGBT, and the device will begin to act as a switch. As the voltage applied to the gate of the IGBT is increased, the collector-emitter current will increase accordingly. This will lead to the IGBT entering into its linear mode and providing a near-constant voltage drop between the collector and emitter sections.

In conclusion, the IXGK120N120A3 is a high-power, IGBT power switch module for AC and high frequency DC motor control. The device utilizes an intelligent control system for robust protection and smooth performance, and its low power losses, high switching speed, and wide voltage range mean that it will be well suited for applications requiring high current handling capabilities. As such, this IGBT module is an excellent choice for use in a variety of industrial or power conversion applications.
