Power Semiconductor Module

Power semiconductor modules are modular devices that integrate one or more power semiconductor chips (such as IGBTs, MOSFETs, diodes, etc.) with driver circuits, protection circuits, thermal management structures, and terminal connections into a single package. Their core function is to optimize electrical performance and thermal efficiency through integrated design, reduce external wiring losses, and simultaneously enhance system reliability and integration. Featuring high power density, low switching losses, strong interference immunity, and ease of installation and maintenance, these modules adapt to diverse power conversion requirements across various power levels. They find extensive application in new energy vehicles (electronic control systems), photovoltaic and wind power (inverters), industrial variable-frequency drives (motor drives), and rail transit (traction converters). As core components in power electronics systems, they enable efficient electrical energy control and conversion.
