摘要： In order to suppress distortion in part of a waveform for a sinusoidal voltage generated by one of a pair of serially connected switch elements effectively turning on during an on/off deadtime in a circuit of a type provided with an on/off deadtime for the pair of switching elements, the power conditioner of the present invention comprises a first and second group including two switching elements each connected in inverse-parallel and in series. The power conditioner alternately turns on and off both switching elements in the first group at a prescribed chopping frequency and alternately turns on and off both switching elements in the second group at a PWM frequency higher than the chopping frequency. In addition, if control is performed with a deadtime provided in the on/off timing for both switch elements in each group, the power conditioner adjusts and controls the on/off duty for the second group switching elements to correspond to the effective on drive in one switching element by each diode during the dead time for each switching element in the first group.

摘要： A solar power generation system (100) which has a solar cell (110), converts an output of the solar cell (110) to predetermined AC power and outputs the converted AC power includes a voltage application part configured to apply an DC voltage to the solar cell (110) and to perform an output recovery operation, and a stop control part (153) configured to stop applying of the DC voltage when a stop condition is satisfied after the DC voltage is applied. Further, when an output correspondence information acquisition part (151) that acquires output correspondence information indicating a value corresponding to an output value of the solar cell (110) is provided, stop control part (153) determines that the stop control part (153) satisfies the stop condition and stops the applying of the DC voltage when the output value corresponding to the output correspondence information exceeds a threshold value.

摘要： The disclosed power conditioner suppresses generation of voltage spikes in a part of a generated sinusoidal voltage waveform. The offset between the timing of chopping, which depends on whether the voltage difference between the voltage of a third pulse voltage series and a sinusoidal voltage is positive or negative, and the timing of the switching between on/off duty cycles of a seventh and eighth element (16, 17), is calculated, and the on/off duty cycles of the aforementioned seventh and eighth elements (16, 17) are controlled on the basis of the aforementioned timing offset.
