Understanding IGBT Technology

Insulated gate bipolar transistors (IGBTs) are three-terminal power semiconductor devices commonly used as switches, in motor control applications, and in power supplies. IGBTs combine the advantages of bidirectional power MOSFETs and bipolar junction transistors (BJTs), providing superior switching performance and a wider range of applications than either device alone.

IGBTs work by combining the benefits of two distinct components: an insulated gate MOSFET that controls current and voltage, and a bipolar junction transistor that provides fast switching speeds. The insulated gate MOSFET is responsible for controlling current and voltage at the collector and drain, and the bipolar junction transistor is responsible for providing a fast on and off signal. A combination of these two components allows for a great degree of power and control over current and voltage.

Additionally, the module is highly suitable for a variety of safety critical applications thanks to an integrated diode to ensure silent and reliable operation.

Working Principle

An AOK75B60D1 insulated gate bipolar transistor module is designed to take an input dc power supply and turn it into an ac waveform. This waveform is then converted back into the form of dc power that the application requires. This is accomplished in two stages.

The first stage is the device\'s upper switch. The upper switch is composed of an insulated gate bipolar transistor that is switched to create a high-current bipolar switch between its collector and emitter. This connection forms a closed loop, allowing current to flow between the collector and emitter when the gate is activated. When the gate is turned off, the current is diverted away from the device.

The second stage of the device is the lower switch. The lower switch is composed of a MOSFET that is used to send the controlled power back to the input dc sources. This allows the device to offer superior regulating capabilities, as the voltage and current can be precisely controlled at the output.

In summary, an AOK75B60D1 IGBT module is capable of converting a dc power supply into an ac waveform, allowing for precise control of the power output. It is an excellent choice for a variety of power control and switching applications, including motor control and industrial automation.
