Title: Inventor Michihiro Tadokoro: Pioneering Innovations in Power Systems

Introduction

Michihiro Tadokoro, an accomplished inventor based in Amagasaki, Japan, is known for his contributions to the field of electrical engineering. With an impressive portfolio of 17 patents, Tadokoro has made significant advancements in power system innovations that enhance efficiency and reliability.

Latest Patents

Among his latest patents, one notable invention is an inverter apparatus designed with control and voltage-sag circuitry to enable quick restarts following mini power failures. This inverter apparatus effectively converts direct current (DC) power from a capacitor, charged via a rectifier circuit, into alternating current (AC) power, which is then supplied to a second AC power system. The design includes several essential components: a discharge circuit, a control circuit, a trigger circuit, a first and second voltage-sag detection circuit, and a control power circuit. The invention ensures that when the second voltage-sag detection circuit detects a dip in the control power circuit's voltage below a specified threshold, the trigger circuit prompts the discharge circuit to discharge any stored charge from the capacitor.

Another significant patent by Tadokoro involves a power system control apparatus and method. A Static Var Compensator (SVC) control section in this system detects the bus voltage through an instrument transformer and adjusts the reactive power generated by the SVC based on the detected voltage. A cooperative control section generates commands to manage the interconnection and disconnection of phase lead capacitors and phase lag reactors based on the SVC's reactive power output and the bus voltage. This invention features a voltage comparator that assesses the bus voltage against a predetermined threshold and oversees the actions of a circuit breaker control section when necessary.
