Title: Naoki Komatu: Innovator in Electronic Ballast Technology
Introduction
Naoki Komatu is a notable inventor based in Kobe, Japan. He has made significant contributions to the field of electronic ballast technology, holding 2 patents that showcase his innovative approach to lamp startup methods and high-voltage discharge lamp lighting devices.
Latest Patents
One of his latest patents is an electronic ballast and method for providing a DC voltage component during lamp startup. This invention involves a discharge lamp ballast designed to generate a DC component in the output voltage during the lamp starting operation. The ballast features an inverter with four switches arranged in a full-bridge configuration, a resonant circuit, and a control circuit. The method includes sweeping the inverter operating frequency within a predetermined range to generate a high voltage for igniting the lamp.
Another significant patent is for a high-voltage discharge lamp lighting device. This device provides a starting pulse voltage sufficient to activate a high-voltage discharge lamp with variable terminal wire connections. It includes a power conversion circuit that rectifies AC input into a predetermined DC voltage output, a charging capacitor, and a full bridge circuit that generates a rectangular wave AC output signal. The device effectively steps up a low pulse voltage to a high pulse voltage, which is then applied to the high-voltage discharge lamp.
