This paper compares the cost and efficiency of two inverter topologies for a 5-kW grid-connected solar inverter application: the Conventional H-Bridge Inverter (CHB) and the Cascaded H-Bridge Multilevel Inverter (CHBMLI). Emphasis is put on power switches and passive elements with a detailed study. To address above mentioned shortcomings, we leverage the intrinsic synchronization and power sharing capabilities of coupled nonlinear Andronov-Hopf oscillators (AHOs) to constitute the decentralized controller of the series-stacked system. The AHO can accept real- and reactive-power setpoints.
