Title: Kiyoharu Inou: Innovator in Power Supply Technology

Introduction

Kiyoharu Inou is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of power supply technology, holding a total of 9 patents. His innovative designs focus on improving the efficiency and controllability of switching power supplies.

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 a switching signal induced in a secondary winding when a direct current input voltage is applied to a primary winding. This signal is rectified and fed to a load, while an output voltage is detected using a switching signal from an auxiliary winding to stabilize the output voltage. The primary, secondary, and auxiliary windings are intricately formed on coil laminate surfaces, optimizing the design for performance.

Another notable patent is a multi-output switching power supply that boasts an improved secondary output. This design achieves high-speed switching and high output voltages by utilizing an auxiliary power supply and a synchronizing signal with a sawtooth waveform. The control signal to an FET switch is significantly reduced in delay time, enhancing the overall efficiency of the power supply. The secondary output circuit is supplied with a square waveform voltage, which is controlled by the FET switch to produce a direct current output voltage with a predetermined value.
