Title: Takahiko Iida: Innovator in DC-AC System Connecting Devices
Introduction
Takahiko Iida is a notable inventor based in Itami, Japan. He has made significant contributions to the field of electrical engineering, particularly in the development of innovative systems for converting and synchronizing power. With a total of 4 patents to his name, Iida's work has had a considerable impact on the efficiency of power supply systems.
Latest Patents
One of Iida's latest patents is a system connecting device that utilizes buck-boost type or buck type chopper circuits and transistors as inverters and power synchronizing switches. This device applies a PWM signal to the transistors of the chopper circuits to convert DC voltage generated by solar cells into positive and negative half-wave AC voltages for an AC power supply. The inverters output AC voltages from their terminals on alternate half cycles, allowing for backflow of power. The power synchronizing switches not only transmit the half-wave AC voltages generated by the inverters to the AC power supply but also insulate one inverter from the AC power supply when the other is in operation. This innovation achieves a DC-AC system connecting device that establishes a ground for both DC and AC sides using minimal components.
Another significant patent by Iida is a pulse generating circuit. This circuit includes means for charging from a DC power source through a resistor to a capacitor. It also features a mechanism for detecting a predetermined charge value of the capacitor, which triggers a main thyristor to discharge the capacitor's charge. The discharge current generates a pulse output to a load, showcasing Iida's ingenuity in circuit design.
