Title: Koji Nakahira: Innovator in Power Supply Technology
Introduction
Koji Nakahira is a prominent inventor based in Kyoto, Japan. He has made significant contributions to the field of power supply technology, holding a total of 8 patents. His innovative designs have advanced the efficiency and functionality of switching power supply units.
Latest Patents
Nakahira's latest patents include a self-oscillation type switching power supply unit. This invention features a switching transistor connected to a primary winding of a transformer, with an oscillation frequency control circuit linked to a feedback winding. The control circuit manages a first controlling transistor, which regulates the delay time when the switching transistor is activated. The system operates in three modes: a rated load mode without delay, a light load mode with a constant or slowly decreasing frequency, and a further decreased frequency mode when a switch is engaged. Another notable patent is an RCC type switching power supply unit, which incorporates a transformer with primary, secondary, and feedback windings. This design includes a main switching element that receives feedback signals and controls the current flow, along with a rectifying and smoothing circuit. A delay circuit is also integrated to prevent the main switching element from turning on immediately after the rectifying element's current drops to zero.
