铁路电力变配电所设计规范
The pwm control of duty cycles acts as an electric transformer which regulates the amplitudes of equivalent input voltage and equivalent output voltage , so that both positive and negative amplitudes of equivalent input voltage are equal to those of equivalent output voltage
对器件占空比的pwm调节，相当于在电路中加入一个电子变压器，使得输入方波电源和输出方波电源的正负电压幅值分别匹配。
This paper proves that the changes of pre - compression on the windings have effects on their natural frequencies and derives their relation , which provides the experimental and theories foundation for fault diagnosis of large - scale electric transformers
通过对大型变压器绕组进行振动实验和根据建立的变压器绕组轴向振动数学模型的理论推导，阐明了变压器绕组预紧力的变化与其固有频率变化之间的关系，这为大型变压器的故障诊断提供了理论与实践依据。
