Abstract
A grid-connected converter device for interfacing a grid network and coupling the grid network to a direct current (DC) source or DC Bus/Network is provided. According to this embodiment, the device includes a neutral-point-clamped inverter circuit having a voltage vacross the DC source or DC Bus/Network, the neutral-point-clamped inverter circuit including one or more switch legs, each switch leg comprising a corresponding pair of switches having an electrical midpoint between the switches of the pair of switches. Said device further including an inductor network coupled to the neutral-point-clamped inverter circuit, the inductor network comprising a set of parallel inductor legs, each parallel inductor leg coupled to a corresponding electrical midpoint of a corresponding switch leg and also coupled to an output electrical node coupled to the grid network. In a variation, the inductor network can include cross coupled inductors, limbed inductors, or filter inductors.
