Transistors - IGBTs – Modules

IGBT modules are transistor power switching devices that combine advanced Insulated Gate Bipolar Transistor (IGBT) and current limiting capability into one compact package. They are commonly used in variety of power control applications such as motor drives, solar inverters, UPS systems, induction heating and welding machines and vehicles systems. One of the most popular IGBT module designs is the APTGT150A120TG module. In this article, we will discuss the application fields of this IGBT module and how it works.

Application Field

This APTGT150A120TG module is mainly used in power conversion and control applications, such as motor drives, solar inverters, switches, and UPS systems. It is ideal for low voltage DC link and PWM drive applications, as well as for traction and UPS applications. It features a low voltage drop and is commonly used to control the speed, torque, and acceleration of motors in industrial, commercial and residential applications.

Working Principle and Features

The APTGT150A120TG module is designed to switch high power DC and AC currents. It is typically used as an on/off device that allows current to flow in one direction when a voltage is applied to the gate terminal. This type of module is designed with an integrated free wheel diode that allows current to dissipate in the event of an overload. The module is rated at 150A peak current and 120A continuous current, which makes it well suited to applications that require high current switching and protection from overloads.

The module also features an isolated postive/negative terminal, which enables it to be used in applications where two voltage sources of different polarities are present. This isolation helps to prevent electrical noise and transients from interfering with the operation of the module. In addition, the module features a built-in transient voltage surge suppressor that helps to protect the device against high voltage transients.

Another key feature of this module is its low voltage drop design, which helps to maximize power efficiency. This is especially important for applications such as motor drives and solar inverters, that require maximum power efficiency. The low voltage drop also helps to reduce the power losses in the device, allowing it to last longer.
