Title: Koji Murata: Innovator in Burst Control Technology

Introduction

Koji Murata is a notable inventor based in Suzuka, Japan. He has made significant contributions to the field of electrical engineering, particularly in the area of resonance converters. His innovative approach has led to the development of a unique patent that addresses key challenges in burst control technology.

Latest Patents

Murata holds a patent for a "Burst controller and burst control method of resonance converter." This invention involves a switching period in a burst cycle that includes three distinct pulses: a start pulse that activates a low-side switching element, a main pulse that engages a high-side switching element, and an end pulse that again turns on the low-side switching element. The patent also describes a burst stop period that corresponds to the load magnitude during a switching stop period. Notably, as the burst cycle approaches a frequency close to the upper limit of audible frequencies, the second off-threshold voltage of the main pulse is adjusted to match the first off-threshold voltage of the start pulse. This adjustment narrows the on-width of the main pulse, effectively reducing the energy transmitted to the secondary side of a transformer and shortening the burst cycle.
