Title: Shigekazu Sugimoto: Innovator in Load Control and Overcurrent Protection Circuits

Introduction

Shigekazu Sugimoto is a notable inventor based in Takahama, Japan. He has made significant contributions to the field of electrical engineering, particularly in the development of load control and overcurrent protection circuits. With a total of eight patents to his name, Sugimoto's work has had a considerable impact on the industry.

Latest Patents

Among his latest innovations is a load control circuit that features a switch device capable of controlling the voltage applied to a load element based on the electric power supply from a power source. This circuit includes a driver circuit that manages the activation and deactivation of the switch device. Additionally, a circuit portion is responsible for setting a duty ratio, which is then output to the driver circuit to regulate the voltage applied to the load element. The duty ratio characteristic curve indicates that as the voltage of the power source increases, the duty ratio decreases gradually, with the rate of decrease becoming smaller over time.

Another significant patent is the overcurrent protection circuit, which consists of a load driver for managing a load, a controller for turning the load driver ON and OFF, and a current sensor that measures the load current. This circuit also includes an add/subtract circuit that performs both addition and subtraction operations on previous calculation results to produce a current calculation result. The controller is designed to turn OFF the load driver when the present calculation result exceeds a predetermined threshold.
