MUMBAI, India, Sept. 5 -- Intellectual Property India has published a patent application (202527076816 A) filed by Mitsubishi Electric Corporation, Tokyo, on Aug. 12, for 'power conversion device, and air conditioner outdoor unit.'
Inventor(s) include Tanaka, Akito.
The application for the patent was published on Sept. 5, under issue no. 36/2025.
According to the abstract released by the Intellectual Property India: "This power conversion device (1) comprises: a rectifier unit (130) that rectifies a first AC power supplied from a commercial power supply (110); a capacitor (210) that is connected to the output end of the rectifier unit (130); an inverter (310) that is connected to both ends of the capacitor (210), and that converts the power outputted from the rectifier unit (130) and the capacitor (210) to a second AC power and outputs that to a load having a motor (314); and a control unit (400) that, by controlling the operation of the inverter (310) so that the inverter (310) outputs to the load the second AC power including pulsations according to the pulsations of the power flowing from the rectifier unit (130) to the capacitor (210), performs capacitor load suppression control that suppresses the current flowing to the capacitor (310). The control unit (400) estimates the capacitor load of the capacitor (210) and determines whether to perform capacitor load suppression control on the basis of the estimated value of the capacitor load."
The patent application was internationally filed on Feb. 22, 2023, under International application No.PCT/JP2023/006456.
