Title: Innovative Contributions of Inventor Hideaki Masui

Introduction

Hideaki Masui, an accomplished inventor based in Makinohara, Japan, has made significant contributions to the field of electrical engineering through his innovative designs and solutions. With a total of 13 patents to his name, his inventions have advanced technology in power supply systems, particularly for vehicles.

Latest Patents

One of Masui's notable patents is the Switching Power Supply Apparatus Using Two Duty-Controlled Pulse Signals for Controlling DC/DC Converter. This invention introduces a sophisticated DC/DC converter that transforms a power supply voltage from an Electric Double-Layer Capacitor (EDLC) by managing the switching of a Field Effect Transistor (FET). The control unit initiates this process with a pulse-width modulation (PWM) signal that decreases in duty from 100% as the converter powers up. Subsequently, it produces a second PWM signal that modulates the output voltage or current to match a designated reference value.

Another significant invention by Masui is the In-Vehicle Power Supply Device. This innovation includes adjustment units that accommodate electric components influencing the impedance of power supply outputs. The unique design allows for easy modification to suit different vehicle types without necessitating changes to the main body of the power supply, thereby achieving effective noise reduction through simple adjustments. This adaptability significantly reduces costs as the same components can be utilized across various applications.
