Systems for power module assembly for inverter

A system comprising a power module for an inverter, the power module including:

• a first inverter to be connected to a first end of a winding of a motor and to be connected to a voltage source, wherein the first inverter is configured to output first AC power to the first end of the winding;
• a second inverter to be connected to a second end of the winding and to be connected to the voltage source, wherein the second inverter is configured to output second AC power to the second end of the winding;
• and
• a changeover switch to selectively connect and disconnect the second end of the winding to and from a neutral connection, wherein the changeover switch is located external to the first inverter and the second inverter,
• wherein the changeover switch includes two sets of parallel transistors in a back-to-back configuration.

A system comprising:

• an inverter to convert DC power from a voltage source to AC power to drive a motor, wherein the inverter includes:
• a first power module to drive a first winding of the motor;
• a second power module to drive a second winding of the motor;
• and
• a third power module to drive a third winding of the motor,
• wherein each of the first power module, the second power module, and the third power module includes:
• a first inverter to be connected to a first end of a respective winding of the motor and to be connected to a voltage source, wherein the first inverter is configured to output first AC power to the first end of the respective winding;
• a second inverter to be connected to a second end of the respective winding and to be connected to the voltage source, wherein the second inverter is configured to output second AC power to the second end of the respective winding;
• and
• a changeover switch to selectively connect and disconnect the second end of the respective winding to and from a neutral connection, wherein the changeover switch is located external to the first inverter and the second inverter,
• wherein the changeover switch includes two sets of parallel transistors in a back-to-back configuration.
