Application Field and Working Principle of the APTGL90DDA120T3G

The APTGL90DDA120T3G is a type of transistor module from the family of IGBTs (Insulated Gate Bipolar Transistors). IGBTs are a hybrid of bipolar junction transistors and Field effect transistors as they possess characteristics from both.

Characteristics of IGBTs

An IGBT combines four layers of semiconductors to create a structure of alternating N- and P-type material. This structure provides the bipolar current carrying capability of the former, while the thickness of the depletion layer in the latter enables fast switching. As a module, the APTGL90DDA120T3G has several functional advantages - the wide available working voltage range (20V to 1600V), low conduction losses, high-speed switching, and soft switching characteristics.

Application Field of the APTGL90DDA120T3G

Due to its beneficial characteristics, the APTGL90DDA120T3G is widely used in various applications, including energy-saving devices, such as adjustable speed drives and inverters. It is also used in inductive heating control units, server power supplies and UPS systems. With its low conduction losses, tremendous driving power and superior surge current handling, the APTGL90DDA120T3G is often used in ignition systems like electric motorcycles.

Working Principle of the APTGL90DDA120T3G

IGBTs like the APTGL90DDA120T3G consist of an insulated gate that is employed to control the bipolar current path between the two electrodes. By allowing or blocking current, the APTGL90DDA120T3G can either be in "on" or "off" state. A gate control signal (GCS) is sent to the insulated gate which is subsequently connected to the base of the bipolar transistor via a resistor. This GCS acts as an impedance to create a back \' current which aids the flow of the forward current.

Conclusion

The APTGL90DDA120T3G is a robust transistor module with excellent characteristics which makes it an ideal choice for many applications. Its wide operate voltage range, low conduction losses, switching speed and soft switching characteristics make it one of the most preferred options when it comes to energy-saving devices, inductive heating control units and electric motorcycle ignition systems.
