摘要： Instantaneous trip capability is provided to an electronic circuit breaker, which is of the type that generates trip signals by accumulating squares of power line current samples and thresholds the accumulation results. Samples of power line current are taken directly from the current transformer and analog-to-digital converter cascade generating them. The analog-to-digital converter is of an oversampling type, using a delta-sigma modulator. The samples are threshold detected against a prescribed threshold value without previous squaring, integration and detection. The threshold detector result is checked for two consecutive overcurrent indications before an instantaneous trip signal is generated.

3.发明授权Subsampling time-domain digital filter using sparsely clocked output latch 失效使用稀疏时钟输出锁存器的子采样时域数字滤波器

摘要： The plural-phase clocking signal used in a subsampling time-domain digital filter is partially blanked to generate a sparse clocking signal for a clocked data latch that decimates the output signal from the digital filter, to supply it at a subsampling rate as compared to the sampling rate of input signal to the filter. The blanking signal is generated from a counter that counts occurrences of pulses in the plural-phase clocking signal, which counter comprises a ripple-carry adder and another clocked data latch arranged to accumulate successive unit values. This procedure guarantees correct timing of clocking signal for the output latch vis-a-vis the plural-phase clocking signal used in the preceding time-domain digital filter despite the time taken for carry ripplethrough in the counter adder. Digital hardware is conserved by blanking only one phase of the plural-phase clocking signals.
摘要翻译： 在子采样时域数字滤波器中使用的多相时钟信号被部分消隐，以产生用于对来自数字滤波器的输出信号进行抽取的时钟数据锁存器的稀疏时钟信号，以将其与子采样时间信号 输入信号到滤波器的采样率。 消隐信号由计数器产生，该计数器对多相时钟信号中的脉冲发生进行计数，该计数器包括纹波进位加法器和另一个计时数据锁存器，被布置为累积连续的单位值。 尽管在计数器加法器中进行进位纹波的时间，该过程保证输出锁存器对于前一时域数字滤波器中使用的多相时钟信号的时钟信号的正确定时。 数字硬件通过仅消除多相时钟信号的一相来节省。
