Modular IGBT and single tube IGBT are two different packaging forms, and they have significant differences in multiple aspects:
Packaging form:
The packaging of single tube IGBT is relatively small, usually using packaging such as TO-247 or TO-220. This packaging makes it more suitable for low-power applications.
Modular IGBT is an electronic module that integrates multiple IGBT transistors, free wheel diodes, and driving circuits. It adopts larger module packaging, and this integrated design can easily achieve high-power applications.
Structure and composition:
The packaging form of IGBT single tube is relatively simple, usually with only one IGBT transistor, one reverse recovery diode, and an optional temperature sensor.
In contrast, the packaging form of modular IGBTs is more complex, including not only IGBT transistors, reverse recovery diodes, and temperature sensors, but also multiple components such as leakage inductance, filtering capacitors, amplifiers, and control circuits.
Performance and application:
The power consumption of IGBT single transistor is relatively low, but its reliability is also relatively high. Due to its small packaging, it is suitable for low-power applications.
Modular IGBT has higher reliability and stability due to the integration of multiple components. It is more suitable for high-power applications such as AC motors, frequency converters, amplifiers, etc.
Selection and considerations:
When selecting an IGBT, factors such as voltage level, current capacity, switching frequency, thermal stability, reliability, cost, and compatibility of the driving circuit need to be considered. The selection of single tube and modular IGBTs also needs to be determined based on specific application scenarios and power requirements.
Overall, modular IGBT and single tube IGBT each have their own characteristics and applicable scenarios. When choosing, it is necessary to comprehensively consider various factors based on specific application and system requirements.
