  • Publication number: 20140347030
    Abstract: Provided are a ramp circuit and a DC-DC converter. The ramp circuit generates a current flowing in a resistor using voltages affected by an output voltage and an input voltage of a DC-DC converter, and generates a ramp signal through copying of the current and charging and discharging of a capacitor using a current mirror unit. The ramp signal is generated by considering the input voltage and the output voltage, and thus the ramp signal has an optimal slope to provide an adaptive response to state change in the input voltage and the output voltage. The DC-DC converter uses such a ramp circuit to facilitate its operation.

    Abstract: Embodiments of the invention provide systems and methods for detecting a sustained arc in an electrical system. Over a time period, current and voltage data for a load signal are collected, from which spectral information is extracted. The spectral information has a frequency component and an amplitude component. The load signal is processed to remove a line frequency signature from the spectral information. One or more sub-harmonic frequency bands are extracted from the load signal and analyzed to determine the presence of an arc signature therein. The sub-harmonic frequency bands may be centered on frequencies corresponding to an integer number of half line cycle periods. Analysis of the sub-harmonic frequency bands can include detecting the peak amplitudes of the rectified sub-harmonic frequency bands to obtain an indicator signal and determining if the indicator signal exceeds a threshold that indicates the presence of the sustained arc.

    Abstract: Embodiments of the invention provide systems and methods for detecting a sustained arc in an electrical system containing polymer-based, semi-conducting components which derive their conductivity from carbon black, carbon nanotubes or other conductive materials. Over a time period, current and voltage data for a cable signal are collected, from which spectral information is extracted. The spectral information has a frequency component and an amplitude component. The cable signal is processed to remove a line frequency signature that includes the electrical system's line current frequency and its harmonics. One or more off-harmonic frequency bands are extracted from the cable signal and analyzed to determine the presence of an arc signature therein. Analysis of the off-harmonic frequency bands can include applying a matched filter to the off-harmonic frequency bands to obtain an indicator signal and determining if the indicator signal exceeds a threshold that indicates the presence of the sustained arc.

    Abstract: A signal integrity test system includes a signal generator, a CPLD, and an indicating light. The signal generator is electrically connected to an input end of transmission lines to generate a simulation signal having a waveform simulating a waveform from a signal source. The CPLD includes a switching module, a sampling module, and a judging module. The switching module generates a sampling clock corresponding to the waveform of the simulation signal. The sampling module is electrically connected to the switching module and samples the simulation signal by the sampling clock, and then transmits a sampling result to the judging module. The judging module compares the sampling result with a standard waveform and displays a comparison result through the indicating light. The disclosure further provides a signal integrity test method.

  • Publication number: 20140347069
    Abstract: In a method for detection of an arc in a current path of a converter arrangement (2) for converting a DC input power to an output power, an arc is detected by sensing the current (4) in the current path by means of a current transformer (11), filtering the current signal (4?) with an analog band pass filter (14), converting the analog filtered current signal (4?) into a digital current signal (4??), determining the harmonic content (19) of the digital current signal (4??) and then deciding whether an arc exists if the harmonic content (19) exceeds a threshold, where the threshold is determined at the beginning as a multiple of the average harmonic content during a certain period of time of the current signal.

    Abstract: A measuring apparatus is connected to a cable to perform testing and diagnosis of the cable. The measuring apparatus includes a voltage source, a resistance, a switch, and an inductance forming a charging circuit, and two anti-parallel thyristors or switched diodes together with the inductance forming a series resonant circuit loop. The apparatus produces a low frequency alternating voltage signal train including a low frequency test signal followed by a low frequency diagnostic signal. The diagnostic signal is a damped decaying signal oscillation in the resonant circuit connected to the test cable. At least one of the signals is bipolar. Both cable testing and cable diagnosis can be performed using the same single measuring apparatus in a single measuring procedure.

    Abstract: A detection coil is incorporated in a self-oscillation circuit. The oscillation frequency of the self-oscillation circuit, which comprises the coil and a capacitor, is set to a high frequency band (e.g., around 1 MHz or higher). A target section whose relative position to the coil section varies in response to displacement of a detection object, and includes a magnetism-responsive member constructed to cause inductance of the coil to vary with the relative position. A rectifier circuit extracts an amplitude level of an oscillation output signal of the self-oscillation circuit and outputs the extracted level as detected position data. For example, a plurality of self-oscillation circuits are provided. Alternatively, a single self-oscillation circuit forms a plurality of series circuits by, for each coil pair, connecting in series the two coils of the coil pair, and includes the result of connecting the series circuits in parallel as an inductor element for self-oscillation.
