探讨了有关变频电机绝缘材料寿命评估用方波脉冲电源性能和结构的一些问题,包括选择波形、提高峰峰值、加快上升时间以及频率、负载电容和功率的关系等,提出了解决问题的方法,并以研制8kV峰峰值双极性对称方波脉冲电源的实例,介绍了解决问题的一些具体措施.
Some problems about the performance and structure of square wave pulse power for assessing the life of inverter motor insulating materials were discussed; and methods to solve the problems were proposed, including the selection of waveform, increasing of peak-peak value, speeding up of rise time and improvement of relationship among frequency, load capacitance and power. Some specific measures to solve the problems in developing an 8kV peak-peak value bipolar symmetric square wave pulse power were presented.
