  • Patent number: 12683533
    Abstract: Disclosed solutions relate to electrical inverters. In an example, a system including an inverter to convert DC power from a voltage source to AC power to drive a winding of a motor is disclosed. The inverter includes a first power module, which includes a first inverter to be connected to a first end of the winding and to be connected to the voltage source. The first inverter is configured to output first AC power to the first end of the winding. The first power module includes a second inverter to be connected to a second end of the winding and to be connected to the voltage source. The second inverter is configured to output second AC power to the second end of the winding. first power module includes a changeover switch to selectively connect and disconnect the second end of the winding to and from a neutral connection.

  • Publication number: 20250286492
    Abstract: Disclosed solutions relate to electrical inverters. In an example, an inverter to convert DC power from a voltage source to AC power to drive a motor is disclosed. The inverter includes a first power module. The first power module includes first phase switches, second phase switches and positive DC power tabs connected to a positive DC rail to provide positive DC power to the first phase switches and the second phase switches. The inverter further includes negative DC power tabs connected to a negative DC rail to provide negative DC power to the first phase switches and the second phase switches. The inverter further includes first phase AC power tabs to receive AC power from the first phase switches. The inverter further includes second phase AC power tabs to receive AC power from the second phase switches.
