  • Patent number: 10027114
    Abstract: A solar module device with the master circuit generates the timing signal to synchronize each of the synchronized half wave rectified DC waveform generated by each of the slave circuits to a grid AC signal or a reference AC signal to allow the DC-AC power conversion of a plurality of solar cell groups provided in a module in an on-grid application and an off-grid application.
    Type: Grant
    Filed: December 31, 2012
    Date of Patent: July 17, 2018
    Assignee: MPOWERSOLAR INC.

  • Patent number: 9356537
    Abstract: An inverter device for a solar module. The inverter device comprises a slave circuit device that includes an input comprising a DC input from a solar cell group and a preliminary boost circuit. A DC boost circuit is coupled to the preliminary boost circuit and configured to boost the intermediary voltage to an AC RMS peak voltage. A rectifier circuit is coupled to the DC boost circuit. An energy recovery circuit comprises a storage device coupled to the rectifier output. The energy recovery circuit is configured to temporarily store a reverse recovery charge and transfers the reverse recovery charge to an output of a DC bus structure to reduce a diode recovery loss in the rectifier circuit.
