Abstract: incandescent lamp works well with a TRIAC dimmer because it is purely resistive. Therefore, in order to design a LED driver compatible with TRIAC dimmer, the input characteristics of the LED driver should be , the same RMS voltage that the TRIAC dimmer alters when dimming the LED. Therefore, through the relationship between ILED and VRMS shown in Equation 18, LED brightness can be controlled by the TRIAC dimmer , current spikes. These large current spikes are induced in the input line when the TRIAC in the dimmer is
