Transistors - IGBTs - Modules

The APTGF90SK60TG is an Insulated Gate Bipolar Transistor Module used in power electronics applications. It is a six-pin package designed for a wide variety of medium-speed, low- to medium-voltage, low-power applications. The module provides high speed switching and high current carrying capacity with high surge current capability. It is capable of handling very low and high off-state voltage without damage to the module and maintains a safe operation level. The module can be used for interfacing and controlling electrical systems, including motor speed control, audio power amplification, and power switching.

Structural Components

The module comprises two main components: an insulated gate bipolar transistor (IGBT) and a driver. The IGBT is responsible for switching and controlling current, while the driver provides the control signals necessary to switch the IGBT. The IGBT is dissipative and consists of two distinct terminal structures: an emitter and a collector. The emitter is the output terminal and transfers current when the transistor is active while the collector is the input terminal and receives the current transferred from the emitter when the transistor is active. The IGBT also contains an independent terminal known as the gate, which is used to control the transistor\'s switching behavior.

Working Principle

In the APTGF90SK60TG, the IGBT is connected in series with the driver, which provides the control signals necessary to switch the IGBT. When the driver receives a signal to turn ON, it generates a voltage across the gate of the IGBT. This voltage opens the gate, allowing electrons to flow from the emitter to the collector, thereby switching the IGBT ON and allowing current to flow from the collector to the emitter. When the driver receives a signal to turn OFF, the voltage is removed from the gate, closing the gate and halting the electron flow between the emitter and collector. This process switches the IGBT OFF, preventing current from flowing from the collector to the emitter. The driver maintains the gate signal for a predetermined time, allowing for stable switching of the IGBT.

Applications

The APTGF90SK60TG has a wide range of applications. It can be used for motor speed control, audio power amplification, power switching, power conditioning, and power supply design. It is also used in applications that require low voltage and high-speed switching such as power supplies, DC/DC converters, and motor control circuits. Moreover, it is suitable for use in motor controllers, automotive electronics, home appliance controls, and power conditioning systems.
