==MOTOR DRIVING APPARATUS - A simplified explanation of the abstract==


This abstract first appeared for US patent application 17985354 titled 'MOTOR DRIVING APPARATUS

==Simplified Explanation==

The patent application describes a motor driving apparatus that includes a motor with windings for multiple phases, a first inverter providing AC voltage to one end of the windings, a second inverter providing AC voltage to the other end of the windings based on the status of a changeover switch, and a controller to control the changeover switch based on the motor driving mode. The changeover terminals of the second power modules are short-circuited to each other.

* The motor driving apparatus includes a motor with windings for multiple phases.
* A first inverter provides AC voltage to one end of the windings.
* A second inverter provides AC voltage to the other end of the windings based on the status of a changeover switch.
* A controller is used to control the changeover switch based on the motor driving mode.
* The changeover terminals of the second power modules are short-circuited to each other.

== Potential Applications ==
* Electric vehicles
* Industrial machinery
* Robotics
* HVAC systems

== Problems Solved ==
* Simplifies motor driving apparatus by using a first and second inverter.
* Provides flexibility in controlling the changeover switch based on motor driving mode.

== Benefits ==
* Improved motor control and efficiency.
* Simplified design and reduced complexity.
* Enhanced flexibility in motor driving modes.


==Original Abstract Submitted==

A motor driving apparatus includes a motor including windings respectively corresponding to a plurality of phases, a first inverter including at least one first power module and providing an AC voltage corresponding to each of the phases to one end of the windings, a second inverter including a plurality of second power modules each including a changeover switch and providing the AC voltage corresponding to each of the phases to the other end of the windings based on information indicating whether the changeover switch is turned on, and a controller connected to the changeover switch and configured to control whether the changeover switch is turned on according to a motor driving mode, wherein each of the second power modules has a changeover terminal to which a first end of the changeover switch is connected, and the changeover terminals of the plurality of second power modules are short-circuited to each other.
