  • Single-phase multi-level asymmetric inverter with AC-bypass and asymmetric modulation strategy
    Patent number: 11005388
    Abstract: A multi-level inverter includes a coupling to a DC power source and a coupling to an AC power source, a plurality of capacitors arranged to create a set of nodes, and a plurality of switches located between the capacitors and the AC power source. Switches are configured to create an AC bypass in which the capacitors coupled to the DC power source may be isolated from the AC power source. The AC bypass is utilized as one of the switching states in a switching sequence that provides enhanced performance including but not limited to reduced electromagnetic interference and ripple.
