Patent number: 11936306Abstract: In an MMC-based power conversion device, a control device generates, for each leg circuit, a first voltage command value not based on circulating current circulating between a plurality of leg circuits and a second voltage command value based on the circulating current. A plurality of individual controllers are provided respectively corresponding to a plurality of converter cells and generate a gate control signal for controlling turning on and off of a switching element of the corresponding converter cell, based on the first voltage command value and the second voltage command value. When generating the gate control signal using pulse width modulation, each individual controller modulates a carrier signal in accordance with the second voltage command value such that the pulse width of the gate control signal changes in accordance with the second voltage command value.Type: GrantFiled: September 9, 2019Date of Patent: March 19, 2024Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Fuminori Nakamura, Takeshi Kikuchi, Daisuke Yamanaka, Takuya Kajiyama, Toshiyuki Fujii
