摘要： The present invention relates to a signal-processing method for detecting a quench of a superconducting magnetic operating current. A quench-detecting apparatus for detecting a quench of a superconducting coil comprises: measuring means installed on a normal busbar which supplies current to the superconducting coil to measure the current of the superconducting coil; and processing means for interpreting the measurement value obtained by the measuring means through a mathematical algorithm to output a measurement value. The signal-processing method for outputting a measurement value from the processing means and detecting a quench of a tokamak system comprises: a step of removing a voltage offset from the measurement value of the secondary voltage detected by the measuring means; a step of removing the voltage noise of the second voltage using an integration method; and a step of removing the drift of a minute voltage for the voltage waveform of the secondary voltage.

摘要： A dual slope A/D converter that eliminates transient errors due to switching of input switches. The unknown voltage is provided to an integrating amplifier through a first switch that is closed prior to the conversion. A second switch is connected to ground and provides ground to the input of the integrating amplifier when closed. The second switch is open prior to the conversion. A third switch is used to short out the capacitor of the integrating amplifier. The initial state of the third switch is closed. When the third switch is opened, the integrating amplifier integrates to a first value. When the first value is reached, the first and second switch change states and the integrating amplifier integrates to a second value. The time period from the first value to the second value corresponds to the unknown voltage.

摘要： A processor [100] includes a plurality of voltage droop detectors [130] positioned at multiple points of the processor. The detectors monitor voltage levels and alerts the processor if a droop event has been detected in real time. Multiple droops can be detected simultaneously, with each detected droop event generating an alert that is sent to a processor module, such as a clock control module, to act based on the detected droop. Each detector employs a ring oscillator [206] that generates a periodic signal and a corresponding count based on that signal, where the frequency of the signal varies based on a voltage at the corresponding point being monitored.

摘要： The average of a complex waveform measured over a time period may be determined by first converting the complex waveform to a voltage, then converting this voltage to a current and using this current to charge a capacitor. At the end of the measurement time period the voltage charge (sample voltage) on the capacitor may be sampled by a sample and hold circuit associated with an analog-to-digital converter (ADC). Then the voltage charge on the sample capacitor may be removed, e.g., capacitor plates shorted by a dump switch in preparation for the next average of the complex waveform sample measurement cycle. The ADC then converts this sampled voltage charge to a digital representation thereof and a true average of the complex waveform may be determined, e.g., calculated therefrom in combination with the measurement time period.
