ROTATING ELECTRICAL MACHINE CONTROL DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18266997 titled 'ROTATING ELECTRICAL MACHINE CONTROL DEVICE
Simplified Explanation
The abstract describes a control device for a rotating electrical machine that shifts between synchronous five-pulse control and asynchronous pulse-width modulation control based on the operating point crossing specific boundaries.
- The control device shifts to synchronous five-pulse control when the operating point crosses a second boundary.
- The control device shifts to asynchronous pulse-width modulation control when the operating point crosses a first boundary.
- The first boundary is determined by comparing the number of switching pulses per unit rotational speed between the two control methods.

Original Abstract Submitted
A rotating electrical machine control device shifts a control system to synchronous five-pulse control when an operating point crosses a second boundary from a state in which asynchronous pulse-width modulation control is being executed, and shifts the control system to the asynchronous pulse-width modulation control when the operating point crosses a first boundary from a state in which the synchronous five-pulse control is being executed. The first boundary is set such that the number of switching pulses per unit rotational speed by the synchronous five-pulse control immediately before the operating point crosses the first boundary is smaller than the number of the switching pulses per unit rotational speed by the asynchronous pulse-width modulation control immediately after the operating point crosses the first boundary.
