Latest Patents

Masaki Nakai holds a patent for an "Inverter controller and method for operating the same." This invention features an inverter controller that utilizes an AC motor as a load. The design includes a rectifying circuit that converts AC power from an AC power source into DC power. A smoothing capacitor is employed to smoothen the DC voltage from the rectifying circuit. The inverter circuit then converts the DC power supplied via the smoothing capacitor into a desired frequency. Additionally, a current detection circuit monitors the output current of the inverter circuit, while a voltage detection circuit tracks the terminal voltage (Vpn) of the smoothing capacitor. The voltage command calculation circuit computes a voltage command for the AC motor, and the speed command calculation circuit determines a speed command when the AC power source experiences a power failure or when the terminal voltage reaches a specific value. This patent showcases Nakai's innovative approach to enhancing inverter technology.
