Claim Text:
1. An inverter device configured on a back plane of a solar module, the inverter device comprising an energy recovery circuit coupled to a rectifier circuit at a first node and a second node, the energy recovery circuit comprising: a first diode; a second diode; an inductor; and a storage device coupled to a rectifier output from a rectifier circuit, the energy recovery circuit being configured to temporarily store a reverse recovery charge and transfer the reverse recovery charge to an output of a DC bus structure comprising the second node and a third node to reduce a diode recovery loss in the rectifier circuit; wherein the inductor has a first end connected to the first node and a second end connected to the third node, the first diode is connected to the storage device at a fourth node, the first diode and the storage device are connected between the first node and the second node, and the second diode has a first end directly connected to the second end of the inductor and a second end directly connected to the fourth node.
