功率模块是低感应系统设计的关键因素

在高频开关电源应用上寄生电感经常会导致开关装置产生过电压并增加半导体器件的判断损耗。通过引入智能功率模块的设计概念，可以减小系统的总电感、电压应力以及开关损耗。本文介绍了新型功率模块的概念以及其在PCB级电路上的应用，还介绍了新型功率模块所带来的寄生电感，关断过电压以及开关损耗的改进效应。

Power Modules is the Key to Low Inductive System Designs

In fast switching applications parasitic inductance causes excessive voltage at the switching device and increased switch off losses in the semiconductors. With an intelligent module concept the total inductance, the voltage stress and switching losses can be minimized. The following paper describes the nes module concept, the implementation on PCB level and the improvements in parasitic inductance, turn off over voltage and switching losses.
