摘要

一个模型已经开发了一个完全集成的三相逆变器,ECN3067,用于变速驱动器。对集成双极晶体管(IGBT)功率器件采用宏模型,并在PSpice中对整个逆变器进行建模。该模型已被证明可以准确地预测导通状态和开关特性。通过量热测量验证了损耗预测,显示了开关频率和调制方法的影响。对于低开关频率,优化IGBTS的低导通降可以大大减少损耗和扩展功率处理能力。

Implementation and calorimetric verification of models for a three phase inverter power integrated circuit
A model has been developed for a fully integrated three phase inverter, the ECN3067, for use in variable speed drives. A macromodel is used for the integrated bipolar transistor (IGBT) power devices and the complete inverter is modelled in PSpice. The model has been shown to give accurate predictions of on-state and switching characteristics. Loss predictions have been verified by calorimetric measurements to show the effects of switching frequency and modulation method. For low switching frequencies, optimising the IGBTS for low on-state drop can greatly reduce losses and extend power handling capacity.
