Insulated Gate Bipolar Transistors (IGBTs) are power transistors used in applications such as motor drives, robotics, solar inverters, alarms and industrial automation. One particular type of IGBT modules, called APTGLQ100DA120T1G, is widely used in these applications.

In this article, we will discuss the application field and working principle of APTGLQ100DA120T1G.

Application field

APTGLQ100DA120T1G is suitable for use in DC/AC inversion, static relays, UPS, welding machines as well as both high- and low-power switching applications. Owing to its fast switching capability and reasonable price, it has been widely adopted in applications where short-circuit current withstand capability is not a major consideration.

APTGLQ100DA120T1G is a 600V IGBT module with a max current rating of 120A. It has a low switching loss, wide range of operating temperature, and a high current capability. Furthermore, its high Commutation capability ensures smooth switching and good thermal stability.

Due to its various features, APTGLQ100DA120T1G is suitable for use in various motor control applications such as AC drives, stepping motors, and robotic motion control systems. It is also suitable for applications such as solar inverters, alarms and other industrial automation systems.

Working principle

APTGLQ100DA120T1G is an IGBT module that combines an Insulated Gate Bipolar Transistor (IGBT) and a freewheeling diode. The IGBT is a type of transistor that combines the properties of a MOSFET (Metal Oxide Semiconductor Field-Effect Transistor) and a bipolar junction transistor. This provides the IGBT with high switching speed and relatively high current carrying capability.

The working principle of the APTGLQ100DA120T1G IGBT module is based on the fact that an IGBT has two distinct subunits; the collector and the emitter. To turn the IGBT ‘on’, a voltage is applied to the gate of the IGBT, which in turn forms an electric field between the gate and the collector. This electric field then modulates the current flow from the collector to the emitter, enabling the IGBT to conduct current.

When the voltage is removed from the gate, the electric field is reduced and the IGBT turns ‘off’, preventing current flow from the collector to the emitter. The freewheeling diode in the module acts as a safety feature, preventing damaging back EMF when the IGBT turns ‘off’.

The APTGLQ100DA120T1G IGBT module is ideal for applications where a low on-state voltage drop and a good thermal stability is required. With its fast switching capability and reasonable price, it has become popular for use in a wide range of motor control applications.
