Abstract:
1. A power converter comprising: a driver that drives a switching element of a switch circuit to convert input power to the switch circuit into output power of the switch circuit; a first calculator that calculates a value of a first feedback controlled variable based on a value of an output electrical parameter of the switch circuit indicative of the output power of the switch circuit and a command value for the output electrical parameter; a selector that selects, in each cycle, one of the value of the first feedback controlled variable and a value of a second feedback controlled variable as a target value of an input electrical parameter of the switch circuit for a next cycle, the input electrical parameter depending on the input power to the switch circuit; a deviation calculator that calculates, in each cycle, a deviation between a value of the input electrical parameter of the switch circuit and the target value selected by the selector in a previous cycle; a second calculator that calculates, in each cycle, the value of the second feedback controlled variable such that the value of the second feedback controlled variable approaches the value of the input electrical parameter; and a controller that 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.
