Abstract: This invention provides an electronic circuit component authenticity determination method capable of determining whether an electronic circuit component is a component manufactured by an authorized manufacturer. The electronic circuit component is operated under a predetermined condition at the time of manufacturing or initialization of the electronic circuit component. The waveform of power consumption or an electromagnetic wave at the time of the operation is measured and stored as first waveform data. An authenticity determination target electronic circuit component is operated under the predetermined condition. The waveform of power consumption or an electromagnetic wave is measured and temporarily stored as second waveform data. The stored first waveform data is compared with the second waveform data. It is determined that the electronic circuit component is a genuine when the waveform data match. It is determined that the electronic circuit component is a counterfeit product when the waveform data are different.

Abstract: A phase difference detector detects the phase difference between two AC signals at a high speed and with high accuracy. A phase difference computation unit computes the phase difference φr(=φ2−φ1) between two detected voltages v1 (phase angle: φ1) and v2 (phase angle: φ2). The phase difference computation unit uses a sine wave vs and a cosine wave vc generated separately and having the same frequency as the fundamental frequency of the voltages v1 and v2, to perform computation of v2s=v2×vs, v2c=v2×vc, v1s=v1×vs, v1c=v1×vc, and then extracts DC components I2=(−A2/2)·sin(φ2), R2=(A2/2)·cos(φ2), I1=(−A1/2)·sin(φ1), R1=(A1/2)·cos(φ1) at low-pass filters. The phase difference computation unit computes R3=R1×R2+I1×I2 at a complex multiplying unit to obtain R3=(A1·A2/4)·cos(φr), computes I3=R2×I1−R1×I2 to obtain I3=(A1·A2/4)·sin(φr), and computes φr=tan−1(I3/R3) at the arctangent calculation unit, thereby obtaining the phase difference φr.

Abstract: A method for detecting a magnetizing inrush current of a transformer includes the steps of obtaining a difference current for each AC phase of a transformer and calculating, for each AC phase, at least two factors for waveform symmetry recognition, on the basis of the difference currents obtained within one period. For each type of factor, one obtains the maximum value of the three factors corresponding to the three AC phases, to serve as a maximum phase factor of that factor. Based on the maximum phase factor obtained, a waveform symmetry recognition algorithm is used to calculate a corresponding waveform symmetry parameter, and if the waveform symmetry parameter meets a requirement for waveform asymmetry, then it is determined that a magnetizing inrush current has occurred. A device for protecting the transformer is further provided.

Abstract: A circuit is provided for detecting peaks of a sinusoidal input signal includes circuitry for generating first and second sinusoidal output signals that are out of phase with one another and with the sinusoidal input signal. A comparator block compares the sinusoidal output signals to determine instances where the amplitudes of the first and second sinusoidal output signals cross over each other. The sinusoidal output signals may lead the sinusoidal input signal somewhat so that, after taking into account processing delay, the indicated crossover instances substantially coincide with peaks in the sinusoidal input signal such that a trigger signal generated by the circuit accurately indicates the timing of the peaks.
