DALI POWER SUPPLY AND CURRENT LIMITERS FOR THE SAME

Disclosed is a power supply (1) for a lighting control bus (2), comprising an isolated power converter (101) configured to inductively supply power from a primary side (102) of the converter to a secondary side (103) of the converter (101); the secondary side (103) comprising output terminals (104)...

Zusammenfassung:Disclosed is a power supply (1) for a lighting control bus (2), comprising an isolated power converter (101) configured to inductively supply power from a primary side (102) of the converter to a secondary side (103) of the converter (101); the secondary side (103) comprising output terminals (104) connectable to the lighting control bus (2); the primary side (102) comprising a switch (105); anda control circuit (106) configured to control, in a first conduction mode of the switch (105), a duty cycle of the switch (105) in dependence of a variation of an output voltage (107) of the power supply (1) measured on the primary side (102), and configured to adjust, in a second conduction mode of the switch (105), a duration of a switching cycle of the switch (105) in dependence of a variation of an average output current (108) of the power supply (1) measured on the primary side (102). This provides a cost and size optimized power supply for a lighting control bus.
