ROTATING ELECTRICAL MACHINE CONTROL SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18032664 titled 'ROTATING ELECTRICAL MACHINE CONTROL SYSTEM

Simplified Explanation

The abstract describes a control system for a rotating electrical machine that can detect open-circuit failures in smoothing capacitors. Here is a simplified explanation of the abstract:

  • The control system monitors the wave height values of currents flowing through two direct-current power supplies.
  • If the difference between the wave height values is equal to or greater than a threshold value and the first wave height value is larger than the second, it indicates an open-circuit failure in the first smoothing capacitor.
  • If the difference between the wave height values is equal to or greater than the threshold value and the second wave height value is larger than the first, it indicates an open-circuit failure in the second smoothing capacitor.

Bullet points explaining the patent/innovation:

  • The patent describes a control system that can detect open-circuit failures in smoothing capacitors in a rotating electrical machine.
  • By monitoring the wave height values of currents flowing through two power supplies, the control system can identify differences that indicate a capacitor failure.
  • This detection method allows for early identification of open-circuit failures, which can help prevent further damage to the electrical machine.
  • The control system can be implemented in various types of rotating electrical machines, such as motors or generators.
  • Detecting and addressing capacitor failures promptly can improve the overall reliability and performance of the electrical machine.


Original Abstract Submitted

When a difference between a first wave height value of a current flowing through a first direct-current power supply and a second wave height value of a current flowing through a second direct-current power supply is greater than or equal to a determination threshold value and the first wave height value is larger than the second wave height value, a control part in a rotating electrical machine control system determines that a first smoothing capacitor has an open-circuit failure, and when a difference between the first wave height value and the second wave height value is greater than or equal to the determination threshold value and the second wave height value is larger than the first wave height value, the control part determines that a second smoothing capacitor has an open-circuit failure.
