Development and Practical Use of Electrical Insulation Diagnosis for Inverter-Fed-Motors in Hybrid-Car under Repetitive Surge Voltages.

本研究的目的不仅是为了开发一套逆变电机重复局部放电起始电压(RPDIV)自动测量系统，而且也是为了促进该测量系统的标准化。在研究过程中，研制了由电力电子电路产生改进型逆变器浪涌的重复性高压脉冲发生器和RPDIV测量系统。最终，采用这两种设备作为国内某生产厂家电气绝缘材料的评价体系。

The purpose of this study is not only to develop an automatic measurement system of repetitive partial discharge inception voltage(RPDIV) for inverter-fed motors but also to promote the standardization of the measurement system. Both a repetitive high voltage pulse generator producing modified-inverter-surges from power-electronics circuits and a RPDIV measurement system are developed during the research period. Eventually, the both equipments are adopted as the evaluation system for electrical insulating materials in a domestic manufacturer.
