Title: Satoshi Yokoo: Innovator in Sensor-less Detection Circuits
Introduction
Satoshi Yokoo is a prominent inventor based in Ota, Japan. He has made significant contributions to the field of sensor-less detection circuits, holding a total of 14 patents. His innovative work has paved the way for advancements in motor control technologies.
Latest Patents
One of Yokoo's latest patents focuses on sensor-less circuits and related methods for back EMF zero crossing detection. This invention includes a sensor-less detection circuit that features a first voltage adjustment circuit, which provides a first output voltage at a first node using one of three input voltages. Additionally, a second voltage adjustment circuit provides a second output voltage at a second node using all three, or only two, of the three input voltages. This second circuit acts as an internal virtual neutral point for detecting a zero crossing event of the motor. A differential amplifier is coupled with the first and second nodes, outputting a third output voltage at a third node. Furthermore, a reference buffer has a reference voltage input and provides a fourth output voltage at a fourth node. A comparator is then coupled with the third and fourth nodes, outputting a fifth output voltage at a fifth node, which indicates a zero cross event.
