Introduction

Tatsuo Oota is a notable inventor based in Fukuoka, Japan. He has made significant contributions to the field of semiconductor devices and power control systems. With a total of 4 patents to his name, Oota's work has had a considerable impact on the industry.

Latest Patents

Oota's latest patents include a "Controller for Power Device" and a "Drive Controller for Motor." The controller is designed to manage a power device in response to an input signal. It features a first signal generator that produces a first signal based on the input signal. Additionally, a level shifter modifies the output level of this first signal to align with the first main power supply potential, resulting in a second signal. A first control signal generator then creates a control signal for a semiconductor device based on this second signal. The level shifter incorporates at least one semiconductor element, which is controlled by the first signal and exhibits specific breakdown voltage characteristics.

The drive controller for the motor comprises at least one power device and control elements for managing these devices. It includes multiple terminals connected to both the power devices and control elements. The design features a support member with a heat sink on its lower surface, while the upper surface accommodates the power devices, control elements, and terminals. This innovative arrangement allows for a compact three-phase motor drive controller, minimizes noise interference, and reduces terminal pitch size.
