Abstract
An electronic power converter includes a storage circuit (101) capable of storing electrical energy that is determined by an electrical quantity, voltage or current, of the storage circuit. The electronic power converter includes an electronic power converter stage (102) connected to the storage circuit and a regulator (103) for controlling the electronic power converter stage to regulate the electrical quantity at least partly on the basis of deviation of the electrical quantity from its reference level. The regulator is configured to weight the deviation with a first gain coefficient when the deviation is positive, and to weight the deviation with a second gain coefficient when the deviation is negative. The first gain coefficient has a value different from that of the second gain coefficient because the reference level is typically not in the middle of the allowed range of variation of the electrical quantity.
