摘要
IPM是一种将驱动和保护电路集成于一体的智能功率器件。为了开发符合 2 1世纪要求的高性能铁道车辆用逆变器 ,日本铁路采用了世界上最新的功率器件——高耐压智能模块 (HVIPM) ,从而使原来采用 3点式逆变电路改为 2点式 ,大大简化了电路 ,缩小了体积 ,减轻了质量 ,提高了可靠性。本文介绍了 3.3k V
IPM is an intellectual power appliance in which the driving circuit is integrated with the protective circuit.In order to develop the inverters for railway cars which have high performance and can meet requirements of the 21st century,the latest power appliance in the world——intellectual module with high voltage endurance(HVIPM)——is applied by the Japan Railway,thus,the point type inverter is changed into the two point type,the electric circuit is simplified greatly,the volume is reduced,the quality is lightened,and the reliability is improved.In this paper,the application of the 3 3 kV HVIPM appliances on railway cars in Japan is described.
