摘要： There is provided an inverter apparatus islanding operation detecting method capable of surely detecting an islanding operation with a simple construction. A distortion for causing a variation in an output frequency of an inverter apparatus in an islanding operation stage is applied to an inverter output waveform. With this arrangement, even when the inverter apparatus is disconnected from an AC power system in a state in which a power factor of a load impedance is proximate to one, a frequency variation is generated in an inverter output, thereby ensuring detection of the islanding operation.

摘要： A pulse width of a pulse train signal used for PWM (pulse width modulation) control is monitored. When a variation of the pulse width substantially disappears within a specified time, it is determined that an operating point on an output characteristic curve of a photovoltaic array is located on the open-circuit voltage side of a maximum power point. When the variation of the pulse width does not disappear after the elapse of the specified time, it is determined that the operating point is located on the short-circuit current side of the maximum power point. Based on the determination result, the inverter control is performed such that the operating point follows the maximum power point.

摘要： An active controller suppressing an incoming acoustic wave by active control includes a signal processing unit filtering, an input signal corresponding to the incoming acoustic wave to generate an output signal, an error detecting portion detecting an error between the output signal and a desired response value, and an adapting portion adjusting a filtering characteristic of the signal processing portion according to the input signal, the output signal, and an error signal such that the error is minimized. The signal processing portion includes a non-recursive all zero digital filter filtering an input signal, and a lattice-type multi-stage all pole digital filter further filtering an output signal of the non-recursive all zero digital filter. The adapting portion updates a filter coefficient of the signal processing portion adaptively while clipping an absolute value exceeding one of a filter coefficient of the lattice-type multi-stage all pole digital filter.

摘要： A main adaptive digital filter and a sub adaptive digital filter are provided, and these two adaptive digital filters share a filter coefficient to be controlled. On the side of the main adaptive digital filter, the shared coefficient is updated so that the difference between the output and a desired response is minimized and on the side of the subadapted digital filter, the above-stated shared filter coefficient is updated so that the output is minimized. A prescribed limitation is given to the frequency characteristic of a filter coefficient to be adapted, by treating the input of the sub adaptive digital filter as a signal weighted on the frequency or a noise having its band limited with respect to the input signal or the output signal of the main adaptive digital filter, and coefficient updating control is conducted so that the coefficient will not go beyond the limitation.
