Title: Innovations of Yoshitaka Onishi
Introduction
Yoshitaka Onishi is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of electrical engineering, particularly in the development of technologies for electric vehicles. With a total of 6 patents to his name, Onishi continues to push the boundaries of innovation.
Latest Patents
One of his latest patents is a charging device for electric vehicles. This device includes a wireless power receiving component that captures high-frequency AC power in a non-contact manner. Additionally, it features a wired power receiving device connected to an external power source for low-frequency AC power. The system incorporates a rectifier that converts AC power, an electric power converter located at the rear of the rectifier, and a switching mechanism that allows for the output of electric power from either receiving device. A high-frequency filter is also integrated to eliminate high-frequency components between the rectifier and the electric power converter.
Another notable patent involves a motor drive system. In this system, if a bus current exceeds a predetermined cutoff value, an overcurrent detector signals a gate driver to turn off switching elements, thereby interrupting the current to the motor. Furthermore, when an overcurrent is detected, a feedback controller instructs the gate driver to apply short-circuit braking after the power supply is cut off, allowing for a reset of the duty ratio command value to zero.
Career Highlights
Yoshitaka Onishi is currently employed at Mitsubishi Electric Corporation, where he applies his expertise in electrical engineering to develop innovative solutions. His work has been instrumental in advancing technologies that enhance the efficiency and functionality of electric vehicles.
