Publication number: 20240146171Abstract: A power converter employing a plurality of parallel high-frequency switching legs, and a low-frequency switching leg, is disclosed. A load may be coupled between the high-frequency switching legs and the low-frequency switching leg. A number of levels of a power waveform produced by the power converter may be higher than the number of levels of the high-frequency switching legs. The low-frequency switching leg may employ switches which may have low switching frequency characteristics, low conduction losses, and may be less expensive.Type: ApplicationFiled: October 20, 2023Publication date: May 2, 2024Inventors: Ilan Yoscovich, Tzachi Glovinsky, Daniel Zmood, David Avraham

Patent number: 11557983Abstract: A multi-level inverter topology is disclosed. A power converter circuit converts a DC source at its input to provide an alternating current (AC) at its output. The power converter circuit may have a controller operably attached to multiple series connections of switches. The controller may control one or more of the multiple series connections of switches to convert a DC input to provide multi-level AC voltages with DC offset across two terminals of the power converter circuit. The multi-level AC voltages with DC offset may then be converted by use of a plurality of series connections of switches to provide a single-phase AC voltage at a first output terminal with respect to at least one of a neutral potential, an earth potential, or a terminal of the power converter circuit.Type: GrantFiled: January 13, 2021Date of Patent: January 17, 2023Assignee: Solaredge Technologies Ltd.Inventors: Daniel Zmood, Ohad Fried, Omer Szlafsztein
