Abstract
In a power converter, a driver drives a switching element using a manipulated variable therefor to convert input power into output power. A first measuring unit measures a value of a first electric parameter depending on the input power. A first determiner determines, from the measured value of the first electric parameter, a first feedback controlled variable. A second measuring unit measures a value of a second electric parameter indicative of the output power, and a calculator calculates, based on the measured value of the second electric parameter and a command value for the second electric parameter, a second feedback controlled variable. A selector selects, based on the measured value of the first electric parameter, one of the first feedback controlled variable and the second feedback controlled variable. A second determiner determines the manipulated variable using the selected one of the first and second feedback controlled variables.
