MUMBAI, India, Aug. 8 -- Intellectual Property India has published a patent application (202517066964 A) filed by Tmeic Corporation, Tokyo, on July 14, for 'control device for power conversion apparatus, and power conversion apparatus.'
Inventor(s) include Tawada, Yoshihiro; and Yamabe, Kenta.
The application for the patent was published on Aug. 8, under issue no. 32/2025.
According to the abstract released by the Intellectual Property India: "A power conversion device control device comprising: an effective power calculation section that acquires an electric current value and a voltage value measured on an AC side of a power conversion device, and calculates an effective power value, which is a measurement value for the effective power output by the power conversion device, on the basis of the acquired electric current value and voltage value; an integration unit that acquires the effective power value from the effective power value calculation section and, only when the acquired effective power value is in a charging direction, integrates the effective power value to calculate a charging power; a gain unit that calculates a first control value obtained by multiplying the charging power integrated by the integration unit and a prescribed gain; a DC voltage determination section that acquires the first control value calculated by the gain unit, calculates a DC voltage value from the charging power on the basis of the acquired first control value, and determines whether the calculated DC voltage value is at or above a prescribed threshold value; and an addition unit that, when it is determined by the DC voltage determination section that the DC voltage value is at or above the prescribed threshold value, adds together a prescribed effective power command value and the first control value and implements P droop control."
The patent application was internationally filed on Jan. 10, 2024, under International application No.PCT/JP2024/000323.
