Introduction
Koichi Nishibata is a prominent inventor based in Kariya, Japan. He has made significant contributions to the field of electrical power converters, holding a total of 8 patents. His work focuses on enhancing the efficiency and reliability of electrical systems.
Latest Patents
Nishibata's latest patents include a drive device for switches and a control circuit for electric power converters. The drive device is designed to perform switching of at least one switch in an electrical power converter. It features a control section that generates and transmits a drive signal for the switch, along with a drive circuit that receives this signal. The control section also generates speed adjustment information to optimize the switching speed of the switch. The drive circuit calculates command switching speed information based on this adjustment information, ensuring precise control of the switching process.
The control circuit for an electric power converter includes an abnormality determiner, a voltage determiner, and an abnormality-handling controller. The abnormality determiner identifies any abnormalities in the electric power converter or a multi-phase rotating electric machine. The voltage determiner checks if the line-to-line voltage between phase windings exceeds the voltage of a DC power source. If an abnormality is detected and the voltage condition is met, the abnormality-handling controller executes an all-phase short circuit control, managing the switches effectively to maintain system integrity.
