Title: The Innovations of Takashi Tsujii
Introduction
Takashi Tsujii is a notable inventor based in Osaka, Japan. He has made significant contributions to the field of power supply technology, holding a total of 3 patents. His work focuses on developing advanced power supply apparatuses for various applications, particularly in lighting systems.
Latest Patents
One of his latest patents is a "Power supply apparatus for arc-generating load." This invention involves a rectifying circuit that converts commercial AC power, which is then supplied to an inverter through a power factor correction circuit. The output from the inverter is transformed in a transformer, rectified again, and applied to a xenon lamp. An igniter's transformer secondary winding is connected to generate an arc in the xenon lamp, with a pulse generator providing short pulses to the primary winding. Additionally, an auxiliary power supply sustains the arc current based on the commercial AC power.
Another significant patent is the "Power supply apparatus for light source." This apparatus includes an input-side rectifier that converts an input AC signal to a DC signal, followed by a high-frequency inverter that transforms the DC signal into a high-frequency signal. An output-side rectifier then converts this high-frequency signal back to a DC output signal for the light source. The system also features power detecting means to monitor the power supplied to the light source, ensuring that a predetermined power value is maintained.
