By a News Reporter-Staff News Editor at Energy Weekly News -- According to news reporting originating from Alexandria, Virginia, by VerticalNews journalists, a patent by the inventors Chen, Wan-Pei (Hsinchu County, TW); Konishi, Yoshihiro (Hsinchu, TW); Huang, Shu-Syuan (Changhua County, TW); Yang, Zong-Zhen (Kaohsiung, TW), filed on December 16, 2015, was published online on February 27, 2018.
The assignee for this patent, patent number 9906119, is Industrial Technology Research Institute (Hsinchu, TW).
Reporters obtained the following quote from the background information supplied by the inventors: "The converter circuit converts an AC power source to a DC power source, or a DC power source to an AC power source. The common application is to use a controller to control the DC side voltage of the converter, and normally reduce the gain of the controller when controlling the DC side voltage of the converter to approach a DC constant."
In addition to obtaining background information on this patent, VerticalNews editors also obtained the inventors' summary information for this patent: "An embodiment of a ripple-compensation control method is disclosed. The method is adopted by a converter controlled by a controller which controls a first voltage of a DC node of the converter according to a command value, comprising: obtaining a ripple-component voltage of the first voltage corresponding to an AC node of the converter; and generating the command value based on the ripple-component voltage and controlling the converter according to the command value.
"An embodiment of an electrical energy conversion device applying ripple-compensation control is disclosed. The electrical energy conversion device comprises a converter configured to perform electrical energy conversion, a controller coupled to control terminals of the converter and controlling a first voltage of a DC node of the converter according to a command value, and a ripple-compensation unit configured to generate a ripple-component voltage of the first voltage and provide the command value generated based on the ripple-component voltage to the controller.
"A detailed description is given in the following embodiments with reference to the accompanying drawings."
