Title: Koichiro Miura: Innovator in Discharge-Lamp Control Technology
Introduction
Koichiro Miura is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of electrical engineering, particularly in the development of discharge-lamp control devices. With a total of 8 patents to his name, Miura's work has had a substantial impact on lighting technology.
Latest Patents
Miura's latest patents include a discharge-lamp control device that features two electrodes and first and second driving units. These units supply power to the discharge-lamp through the electrodes. Each driving unit consists of a transformer with primary and secondary coils, along with a capacitor connected in parallel to the secondary coil. The first driving unit is designed with impedance characteristics that exhibit a minimum impedance at a first frequency and a maximum impedance at a second frequency, which is lower than the first frequency. Similarly, the second driving unit has its own impedance characteristics, with a minimum impedance at a third frequency and a maximum impedance at a fourth frequency, which is lower than the third frequency. The operating frequency of the driving circuit is selected within a frequency bandwidth from the fourth frequency to the third frequency.
Another notable patent is the power supply apparatus and control circuit. This invention includes a selector that sets the respective phases of pulse driving signals in reverse when a proportion signal or integration signal does not exceed a threshold. By shifting the phases of the pulse driving signals, the ripple voltage is lowered. When the load current increases drastically, the output voltage tends to decrease due to a shortage of capacity in the power supply. In such cases, the phase control unit synchronizes the phases of the pulse driving signals to maintain a stable output voltage.
