Abstract: In a power converter, a deviation calculator calculates, in each cycle, a deviation between a value of an input electrical parameter of a switch circuit and a target value selected by a selector in a previous cycle. The input electrical parameter depends on the input power to the switch circuit. A second calculator calculates, in each cycle, a value of a second feedback controlled variable such that the value of the second feedback variable approaches the value of the input electrical parameter. A controller controls, in each cycle, the selector to select one of the value of the first feedback controlled variable and the value of the second feedback controlled variable as the target value for the next cycle according to the deviation calculated by the deviation calculator.

Abstract: An electric power converter has a switching circuit section, a transformer, a rectifier, and a noise filtering element. The rectifier is connected to a secondary coil of the transformer. A closed circuit where the noise current flows is formed by the secondary coil, the rectifier, and the noise filtering element. The transformer and the noise filtering element are disposed in a position next to each other. The secondary coil and the noise filtering element are electrically connected to each other through a terminal for a coil that is a terminal of the secondary coil and a terminal for a filter that is a terminal of the noise filtering element. The terminal for the coil and the terminal for the filter are disposed in a position between the transformer and the noise filtering element.
