MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202617072163 A) filed by Hitachi Industrial Equipment Systems Co. on June 10, 2026, for Power Conversion Device And Inverter Control Device.
Inventors include Yoshida, Naomitsu; Kikuchi, Akira; and Matsunaga, Shunsuke Number.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: Provided is a power conversion device comprising: a first voltage command generation unit that generates a first voltage command on the basis of a predetermined rated voltage; an angular frequency command generation unit that generates an angular frequency command for alternating current power on the basis of an active power command input from the outside; a phase command generation unit that generates a phase command on the basis of the angular frequency command; a current command generation unit that generates a current command for the alternating current power on the basis of the phase command and the first voltage command; a harmonic current command generation unit that generates a harmonic current command; and a current control unit that generates a voltage command for the alternating current power on the basis of the current command generated by the current command generation unit and the harmonic current command generated by the harmonic current command generation unit. The harmonic current command generation unit acquires reference information synchronized with a power system or absolute time information, and determines the phase of the harmonic current command on the basis of the reference information or the time information.
