本标准适用于电子设备中使用的小型低功率脉冲变压器，其峰值工作电压为1000V或更低，传输峰值功率为300W或更低，平均功率为5W或更低。当在规定的阻抗之间工作时，这些变压器需要在规定的振幅和时间公差内转换单极或双极电压或电流脉冲。本标准不包括IEEE Std 272-1970《计算机型（方环）脉冲变压器标准》中涵盖的低功率开关型脉冲变压器。这些变压器依赖于方形变压器的使用- 用于操作的环形磁芯材料，具有存储能力，通常仅传输双极脉冲，除非提供磁芯磁通重置。本标准不包括用于电力转换应用的变压器。变压器将包含在相关标准中。当显示数值时，可将其视为建议值。第2节包含主要与低功率脉冲变压器功能测试有关的术语定义，第5节包含等效电路和相关术语的定义。第6节描述了首选变压器试验方法，附录中包含了备用试验方法。

This standard pertains t o small low-power pulse transformers for use in electronic equipment, transmitting peak power of 300 W or less and average power of 5W or less with a peak working voltage of 1000 V or less. These transformers are required to transform unipolar or bipolar pulses of voltage or current within specified tolerances of amplitude and time when operated between specified impedance. This standard is not intended to include low-power switching type pulse transformers which are covered in IEEE Std 272-1970, Standard for Computer-Type (Square-Loop) Pulse Transformers. These transformers depend upon the use of square - loop core material for operation, have memory capability, and normally transmit only bipolar pulses unless provision is made for core flux reset. This standard is not intended to include transformers for power conversion applications. T h o s e transformers will be covered in a related standard. Whenever numerical values are indicated they may be considered as recommended values. Section 2 contains definitions of terms pertaining primarily to functional testing of low-power pulse transformers, and Section 5 contains equivalent circuits a n d definitions of associated terms. Section 6 describes preferred transformer test methods and the appendix contains alternate test methods.
