摘　　要：为解决在静电陀螺和静电加速度计等高精度惯性仪表中,方波调制高压变压器输出方波发生畸变,降低了波形的实际出力系数的问题,该文对方波变压器的特性进行分析,得出了影响其波形畸变的各种因素。以此为依据设计的一种变压器,获得了最大输出电压1.76kV、出力系数0.92、带宽大于47kHz的优异性能。结果表明,通过对方波变压器的特性进行分析,选择合理的参数和工艺,能够显著提高方波的出力系数。The use of square-wave modulated high-voltage transformers in precise inertial apparatus, such as electrostatically suspended gyroscopes and accelerometers, can significantly improve the bearing capacity. However, the transformer design invariably distorts the square-wave output, which causes the actual foree-voltage faetor to be lower than the theoretieal value. The design characteristics of a square-wave transformer were analyzed to design a transformer with a maximum output voltage of 1.76 kV, force-voltage factor of up to 0. 92 and a bandwidth exceeding 47 kHz. Therefore, analysis of the transformer characteristics can yield appropriate designs that greatly reduce the wave distortion .
