In phase-cut dimming systems, a key technical issue has been mostly TRIAC holding current maintenance with low power LED lamps. In order to continue TRIAC conduction until the line voltage zero crossing, there have been several trials to flatten the driver input current higher than the holding current. In the previous compensation methods to provide constant input current, the input current is not precisely constant with a compensation error.
