Difference between power module and igbt

Power module and IGBT are related but different concepts. The following are the differences between them:

1. Definition:

-Power module: A power module is an electronic device, which usually integrates a variety of power semiconductor devices, such as IGBT, MOSFET, diode, control circuit, heat dissipation equipment, etc. Its purpose is to provide effective power conversion and control.

-IGBT:IGBT is a special power semiconductor device, belonging to insulated gate bipolar transistor. It is an indispensable part of the power module.

2. Function:

-Power module: In addition to IGBT, power module can also include other power semiconductor devices, as well as related control circuits and heat dissipation equipment. The function of power module is to realize efficient conversion and control of electric energy, which is suitable for various power electronic applications.

-IGBT:IGBT is a special transistor used to control current. It is usually used as a switch to control the power flow in high current and high voltage circuits.

3. Application:

-Power module: It can be used in many application fields, such as industrial automation, motor drive, power inverter, solar and wind energy converter, electric vehicle control, etc. They can adapt to different power requirements and application environments.

-IGBT:IGBT is usually used as a part of power module in specific applications, such as inverter, motor control, power amplification, etc.

4. Packaging:

-Power module: It usually includes a housing for isolating internal circuits and providing mechanical protection. The type and size of the housing can vary according to different applications.

-IGBT:IGBT is usually a single semiconductor device, and its package depends on the model and manufacturer. Some IGBT require additional heat dissipation devices to manage the heat generated by the devices.

Power module is a broad concept, which can include all kinds of power semiconductor devices. IGBT is one of the common power semiconductor devices, which is usually used to realize power conversion and control in power modules.
