Benefits Of IGBT IPM

May 18, 2022

Key points of this paper

1. IGBT IPMs offer many advantages in terms of ease of design, safety, reliability and space saving compared to discrete product designs.

2. IGBT IPMs are less customizable, but their essential use is to select the right IGBT IPM according to the application product.

Advantages of IGBT IPM

IGBT IPMs not only have built-in IGBT devices but also have built-in driver circuits and protection circuits, etc., so they have the following advantages.

● When designing circuits using discrete products, specialized technical skills are required to handle power components, but the IPM has built-in power components and incorporates their driving technical skills, making it easy to use.

● The IPM is optimized for power components and driver circuits, and its operation and characteristics are guaranteed, making it easier and time-saving to design peripheral circuits for applications.

● A variety of required protection functions are built-in, allowing safe construction of applications that handle high power.

● Since not only electrical characteristics but also thermal and EMC-related characteristics are taken into consideration, various problems related to board design and component installation can be avoided when designing with discrete products, resulting in higher reliability.

● In a discrete structure, IGBT and IC are in separate packages, so they require a corresponding board area, while IPM basically mounts the bare chip directly on the module board, which is smaller and more space-saving, thus reducing board size, improving efficiency, and simplifying board wiring.

● Since it is a module, the number of components is only one, which helps to improve the reliability of the system.

Compared to designs using discrete products, designs using IPM have many advantages, but if we must list disadvantages, the specifications and characteristics are fixed, so they are not suitable for customized applications such as individual adjustments. However, the specifications of IPM are set assuming the main application and approximate applications, and its original use is to select the appropriate product according to the application.
