Working Principle

The APTGT150DH120G is an advanced IGBT module with insulated gate and bipolar transistor technologies, providing high-efficiency and robust operation. It is a three-terminal power switching device, consisting of a dielectrically-isolated insulated gate bipolar transistor (IGBT) die, emitter collector diodes and gate driver components, housed in a modular package assembled in a robust, thermally-conductive (insulated) case.

The IGBT power switching device provides low gate charge and low on-resistance in a wide supply voltage range of up to 1200V (peak), allowing for high switching rate and energy savings. When the gate signal is applied to the IGBT, it switches on and provides a current path between the emitter and collector.

When the gate signal is removed, the IGBT switches off and redirects the current flow from the emitter to the collector and thus, a short circuit is induced. This process is known as “commutation” and is possible due to the fast switching of the IGBT device. The IGBT die is mounted on a heat-dissipating baseplate with a gate driver component.

The gate driver component controls the on/off state of the IGBT module and provides the necessary voltage to the IGBT gate terminal to switch it on/off. The molded case provides a low thermal resistance and helps to effectively dissipate the heat that is generated during the switching process.

Conclusion

The APTGT150DH120G is a powerful and efficient IGBT module ideal for applications such as motor drives, traction systems, renewable energy systems, and other power conversion circuits. The device provides a wide supply voltage range of up to 1200V (peak), low on-resistance, and fast switching operation, resulting in improved performance and reduced energy losses.
