Intelligent Power Module (IPM): An Overview
An Intelligent Power Module (IPM) is a high-performance power electronic device that integrates power semiconductor devices, gate drivers, protection circuits, and sometimes sensors into a single compact module. IPMs are widely used in modern industrial, automotive, and consumer electronics applications to efficiently control electric motors and other power devices.
What Is an Intelligent Power Module?
An Intelligent Power Module is essentially a smart power device that combines multiple functionalities:
Power Switching Devices: Typically includes Insulated Gate Bipolar Transistors (IGBTs) or MOSFETs for high-efficiency power conversion.
Gate Drivers: Built-in drivers simplify control by providing proper voltage and current to turn power devices on and off.
Protection Circuits: Safeguards against overcurrent, overvoltage, overtemperature, and short-circuits.
Sensors (optional): Monitors temperature or current to enhance system reliability.
By integrating these features, IPMs reduce the need for external components, save space, and improve system reliability.
