Six-Phase Motor Drive Synchronization via Single Controller

The patent combines the control functions of both master and follower controllers into a single controller that generates command signals for both pulse width modulator generators. This unified control architecture eliminates the synchronization issues caused by having separate controllers with independent clocks and timing variations, while still maintaining the six-phase power output capability through coordinated control of the two three-phase power base drive sections.

The patent merges the timing and clock functions into a single controller, ensuring that both pulse width modulator generators receive commands from the same timing source. This eliminates the clock synchronization errors that occur when separate controllers operate independently, while the system maintains adaptability through the single controller's ability to manage both power base drive sections with a unified timing architecture.

The patent segments the six-phase power system into two three-phase power base drive sections that are controlled by a single controller. This segmentation approach maintains the energy efficiency and output power benefits of six-phase systems while using simpler three-phase drive section structures. The single controller coordinates these segmented sections to achieve overall six-phase performance with reduced energy losses.

The patent implements a six-phase system segmented into two three-phase drive sections, which distributes the power delivery across more phases. This segmentation allows for better thermal management and reduced operating temperatures compared to a conventional three-phase system, thereby extending motor winding life. The system maintains ease of implementation by using standard three-phase drive section building blocks coordinated by a single controller.
