The Trouble with TRIACs

• Start of AC cycle TRIAC initially off– C1 charges through R1 and light bulb

• When voltage on C1 exceeds DIAC threshold voltage the TRIAC conducts– R1 controls when TRIAC turns ON, dimming function

• Light bulb load must maintain TRIAC holding current– TRIAC turns off close to zero crossing and cycle repeats

• LED lights do not always consume enough power to keep TRIAC ON– Need to solve this with extra circuitry

Special care is required when making LED lighting compatible to standard TRIAC dimmers

High Light Output Drivers Traditional Solution – Power Supply with PFC and Low Voltage DC output

LED Strings Driven with Multiple Buck Regulators

Traditional Implementation:

PFC Stage - Required in any implementationDC-DC Stage - Provides constant voltage and isolation stageMultiple Bucks - Provides constant current to each LED string

Benefit:• Allows for individual string dimmingDrawbacks: • Controller and MOSFET and Inductor required for each LED string • Decreased reliability due to many extra converters (N-1 compared to SIMPLEDrive)

Power Supply


High Light Output Drivers – PFC + Buck + Multiple Strings

SIMPLEDrive: PFC + DC-DC + Multiple Buck stages

PFC Stage - Required in any implementationLow Side Buck - Provides constant LED Current and main controlSeries Transformers - Provides constant current to each LED string

Benefit:• One control section for all string currents, • Lower part count, higher reliability and lower costDrawback: • All strings will be dimmed simultaneously (if individual dimming is required)
