Transistors - IGBTs - Modules

The APTGT75DA120D1G is a IGBT module designed for use in inverters, UPS, converters, welding machines and other equipment, often for switching and power control purposes. This module provides high power density, high frequency operation and good thermal properties.

The APTGT75DA120D1G module is designed for high voltage applications, with a minimum breakdown voltage of 3.2 kV. It can be mounted on a heatsink and cooled with forced air, water or oil. It is a three-phase IGBT module, with two SCRs, two intrinsic shunts and three series power diodes.

The purpose of an IGBT module is to switch the voltage applied to the load. The power input is applied through three insulated gate transistors (IGBTs), which serve as switches. Each IGBT has an intrinsic free-wheeling diode, which is triggered when the IGBT is switched off. When the IGBTs are open, the reduced voltage will pass through the two shunts and finally through the power diodes.

The switching frequency of the IGBT module is determined by the frequency of the input power. The module operates at peak switch-on speed, allowing the chips to be turned on and off quickly. The module is also designed to withstand short-term overloads.

The APTGT75DA120D1G module is suitable for use in many applications, such as inverters, UPSs, converters, welding machines, etc. It is also used in motor drives and solar applications. Its modular design makes it easy to install and allows for maximum current density. It has a very high input current rate, allowing for fast response times. The module also provides greater efficiency and power density than conventional IGBTs.

In summary, the APTGT75DA120D1G is an IGBT module designed for use in high voltage applications. It has a high current capability, a high switching frequency and can withstand short-term overloads. It is suitable for use in many applications requiring power control, such as inverters, UPSs and converters.
