  • Patent number: 8902620
    Abstract: A power conditioner that suppresses distortion in a waveform of a sinusoidal generated voltage includes a first and second group including two switches each connected in inverse parallel and in series. The power conditioner alternately turns on and off both switches in the first group at a prescribed chopping frequency and alternately turns on and off both switches in the second group at a PWM frequency higher than the chopping frequency. If control is performed with a dead-time provided in the on/off timing for both switches in each group, the power conditioner adjusts and controls the on/off duty for the second group switches to correspond to the effective on drive in one switch by each diode during the dead-time for each switch in the first group.

  • Publication number: 20110221281
    Abstract: A photovoltaic power system continues or stops running according to a degree of a detected capacity leakage of a capacitor in a power conditioner of the system. The capacitor in the power conditioner performs power conversion of an output of a photovoltaic cell to output an output power to the system. A method for detecting the capacity leakage of the capacitor includes: detecting the capacity leakage based on a voltage deviation of a charge voltage between both ends of the capacitor of a detection target of the capacity leakage; suppressing the output power when the detected capacity leakage is a capacity leakage in which the running can be continued by the output power suppression; and stopping the photovoltaic power system provided with the power conditioner when the capacity leakage is a capacity leakage in which the running of the system cannot be continued even if the output power is suppressed.
