It is desirable to get rid of a short circuit as promptly as possible, now breakers can interrupt short circuit currents within two cycles ( on power frequency basis). 对于短路需尽快地摆脱,现在,断路器可在两个周波(对于工频)内开断短路电流。
With the development of the technology, the design of the electronic circuit is getting rid of traditional pattern, while using FPGA to design electronic circuit is becoming the trend of design. 随着科技的发展,电子电路的设计正逐渐摆脱传统的设计模式,而采用FPGA来设计电子电路正成为设计的趋势。
In this paper, the circuit for getting rid of 90 °& 180 ° impulse from Spn Echo Spectrometer is designed, The circuit apply to detect weak Spin Echo Signal together with Boxcar Integrator and Spin Echo Spectrometer, and improved dynamic range greatly. 设计了除去自旋回波谱仪输出的90°脉冲信号电路,该电路的设计可实现利用Boxcar积分器和自旋回波谱仪测量微弱的自旋回波信号,较大地提高Boxcar积分器的输入动态范围。
In the course of measuring luminosity, temperature and velocity of flow, the technology which gets rid of the extreme value and calculates the average value is used. A new kind of circuit which can realize linear transform for the temperature sensor is designed. 对浓度、温度和流量的测量使用去极值平均滤波技术,并设计一种新型采集电路实现了温度传感器输出的线性转换。
Currently, the switching power supply generally uses the traditional analog control method, which cannot get rid of the problems of nonlinearity, error, drifting and ageing existing in the analog control circuit. 现阶段开关电源普遍采用传统的模拟控制方式,无法摆脱模拟控制电路中存在的非线性、误差、漂移、老化等问题。
