METHOD AND SYSTEM FOR SUPPLYING MULTIPLE LED DRIVERS USING THE SAME TRAIC DIMMER

摘要

An RCD transient absorption circuit, having a first port and a second port, the RCD transient absorption circuit comprising a first resistor, a capacitor and a diode, wherein: the first resistor is connected in parallel to the capacitor, and resultant parallel connection of which is connected in series to a diode; one end of the resultant parallel connection of the first resistor and the capacitor is connected to a cathode of the diode; another end of resultant parallel connection is the first port of the RCD transient absorption circuit; and the second port of the RCD transient absorption circuit is an anode of the diode; the RCD transient absorption circuit further comprises a power-trimming device connected in parallel to the first resistor and the capacitor.
