POWER CONVERTER WITH CURRENT FEEDBACK LOOP

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 s...

Zusammenfassung:	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.
