Latest Patents
One of his latest patents is a "System for detection of a ground fault in a high resistance ground network." This method provides a way to detect ground faults in a voltage source power conversion circuit. It involves a power converter that transforms incoming AC power into DC power, which is then applied to a DC bus. An inverter subsequently converts the DC power back into output AC power. The method includes detecting a midpoint-to-ground voltage between the low side of the DC bus and ground potential, allowing for the identification of ground faults in a high resistance network based on the detected voltage.
Another significant patent is the "Ground scheme identification method." This invention includes methods and systems for detecting the grounding condition of an electrical system. It automatically determines a suitable electrical drive configuration. The drive features a test resistor that can be connected or disconnected to measure different drive voltages. The measured voltages are analyzed to ascertain the type of grounding configuration of the electrical system where the drive will be installed. This patent also addresses the determination of ground resistance conditions, such as high resistance ground faults, during the operation of the drive.
