Title: Hironobu Kusafuka: Innovator in Voltage Control Technology
Introduction
Hironobu Kusafuka is a notable inventor based in Miyoshi, Japan. He has made significant contributions to the field of voltage control technology, holding 2 patents that showcase his innovative approach to solving complex engineering challenges.
Latest Patents
His latest patents include a control box for a charger and a voltage generator device for motor vehicles. The control method for the voltage generator device is designed to maintain operation and function during abnormal conditions. Specifically, if a battery voltage drops when an engine is restarted after an idle stop, the voltage raising device increases the output voltage to a target level using a voltage detecting circuit and a current detecting circuit. In cases where an overcurrent is detected, a switching control circuit reduces the target voltage to ensure safe operation. Additionally, an overvoltage detecting circuit outputs a prohibition signal to halt the switching operation if overvoltage occurs. This innovative design enhances the likelihood of successful engine starts under challenging conditions.
