Title: Hiroki Wake: Innovator in Power Supply Technology
Introduction
Hiroki Wake is a prominent inventor based in Chiba, Japan. He has made significant contributions to the field of power supply technology, holding a total of 5 patents. His innovative designs focus on enhancing the efficiency and functionality of power supply circuits.
Latest Patents
One of Hiroki Wake's latest patents is a power supply switching circuit. This invention is designed to efficiently supply a desired voltage among multiple voltages to a load. In the case of a P-type semiconductor substrate, N-type MOS transistors are strategically placed between the load and both the AC adapter and the battery. This configuration eliminates the presence of parasitic diodes, ensuring that there is no unintended current path between the load and the power sources. As a result, when both the AC adapter and the battery are connected, the N-type MOS transistor is turned off, completely cutting off the current path from the battery to the load. This allows only the AC adapter to supply voltage to the load.
Another notable patent is a switching regulator power supply apparatus. This invention aims to provide multiple light-emitting outputs without increasing the total number of structural components. The apparatus includes a switching type power converting circuit, a current detecting circuit that generates a feedback signal based on the load current, and an SWR control circuit that drives the power converting circuit. The SWR control circuit is equipped with a control signal input terminal and a reference voltage circuit capable of outputting various reference voltages based on the input control signal.
