(54) ELECTRONIC CONVERTER, AND RELATED METHOD OF OPERATING AN ELECTRONIC CONVERTER


(57) There is described an AC/DC electronic converter. The converter includes two input terminals for receiving an AC voltage (Vin) and two output terminals (106a, 106b) for providing a regulated voltage (Vout) or current (iout). Moreover, the AC/DC electronic converter includes a rectifier circuit and a boost converter (12) .
The boost converter (12) receives at input, via a positive input terminal (104a) and a negative input terminal (104b), the DC voltage (Vin,DC) generated via the rectifier circuit, and provides at output, via a positive output terminal (106a) and a negative output terminal (106b), the regulated voltage (Vout) or current (iout).
The electronic converter further includes a control circuit (14) configured to drive electronic switch (SB) with switching cycles (TSW) comprising a first interval, wherein electronic switch (SB) is closed, and a second interval wherein electronic switch (SB) is opened.
