Title: Hisanaga Takano: Innovator in Power Supply Technology

Introduction

Hisanaga Takano is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of power supply technology, holding a total of 3 patents. His innovative designs focus on improving the efficiency and controllability of power converters.

Latest Patents

One of his latest patents is a switching power supply using a printed coil type transformer. This invention features an indirect feedback type flyback converter that enhances the controllability of the secondary output voltage. The converter is designed to smooth the switching signal induced in a secondary winding when a direct current input voltage is applied to a primary winding. This is achieved through rectification and feeding the signal to a load, while an output voltage is detected using a switching signal from an auxiliary winding. This design stabilizes the output voltage effectively.

Another significant patent is the laminating type molded coil. This invention includes a method of fabricating a coil substrate structure where coils are formed on both sides of an insulating substrate using a printed wire technique. The process involves resin sheets and insulating covering sheets that, when heated and subjected to pressure, fill the spaces between the layers and coils. This results in an integral structure that is both thin and efficient, eliminating the need for a molding box.
