Abstract: A method of operating an inverter device configured on a back plane of a solar module, the inverter device comprising an energy recovery circuit device coupled to a rectifier circuit, the method comprising transferring a charge from a rectifier output to a storage capacitor configured in an energy recovery circuit; storing the charge at the storage capacitor for a time period associated with a reverse recovery time; and transferring the charge to an output of a DC bus structure to reduce a diode recovery loss in the rectifier circuit.

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.
