Title: Haruka Matsuo: Innovator in Electrical Apparatus and Refrigeration Technology

Introduction

Haruka Matsuo is a prominent inventor based in Tokyo, Japan. She has made significant contributions to the field of electrical apparatus and refrigeration technology. With a total of seven patents to her name, Matsuo continues to push the boundaries of innovation in her industry.

Latest Patents

Matsuo's latest patents include an electrical apparatus and a refrigeration cycler. The electrical apparatus features a substrate that houses circuit components of a power converter, which is powered by an alternating-current supply. It includes a housing that accommodates the substrate, a current detector, and a controller. The current detector is designed to detect a physical quantity correlated with a common mode current, which circulates through the alternating-current power supply, substrate, and housing. The controller is responsible for sensing the connection of a ground wire based on the current detector's readings.

Another notable patent is her power conversion device, which consists of a rectification unit that converts first alternating current (AC) power from a commercial supply. This device includes a capacitor, an inverter, and a control unit that manages the inverter's operation. The inverter outputs second AC power to a load, such as a motor, while reducing the current flowing to the capacitor. Notably, this design does not include a discharge circuit or overvoltage protection circuit for the capacitor.
