Publication number: 20230275517Abstract: An LED converter for supply of an LED load (18) is provided. The LED converter comprises a switched resonant converter (1) having at least one switch (11, 12) controlled by a control unit of the switched resonant converter (1). The control unit is configured to control a switching operation of the at least one switch (11, 12) such that the switched resonant converter (1) supplies an adjustable constant current (17) to output terminals for the LED load (18). The control unit is further configured to generate the adjustable constant current (17) by alternatingly controlling the at least one switch (11, 12) with one of at least two different, and adaptable, switching frequencies (44, 45) at a time for a respective time period (54, 55), and by adjusting a relative duration of the time periods (54, 55). Thereby, a resolution of an output current of the LED converter for supply of the LED load (18) is improved, which is of particular relevance for dimming applications.Type: ApplicationFiled: September 10, 2021Publication date: August 31, 2023Applicant: Tridonic GmbH & Co KGInventors: Jakob Maldoner, Patrick Marte, Patrick Walch
