Latest Patents
One of Okabe's latest patents is a current detection device that includes a current sensor designed to detect magnetic field vectors. This invention aims to provide a further miniaturized and densified current detection device or a power conversion apparatus that incorporates the same. The device features a plurality of conductors corresponding to currents of multiple phases, with the current sensor arranged in a region sandwiched between these conductors. It outputs information on the current flowing in the conductor based on a combination of magnetic field vectors generated by the currents.
Another significant patent is a diagnostic device capable of accurately diagnosing the soundness of a resolver circuit. This device includes a shifter that receives and shifts the level of excitation signals, ensuring that the period of time during which the signals are at the same value is less than a prescribed threshold. A trigger generation circuit then generates a trigger during this period, allowing a control unit to determine any abnormalities in the resolver circuit based on the trigger.
