What is PFC and what does it do?

Power factor correction is abbreviated as PFC, which is mainly to improve the ratio of effective power to apparent power at the input end of a power supply. It is one of the common circuits in led dimmable power supplies. Generally, the power factor of the input end of the model without PFC circuit is only 0.4~0.6, but with active PFC circuit, it can reach more than 0.95 Active power factor correc...

Why should LED be driven with constant current?

First, the output current of the dimmable constant current led driver is constant, and the output voltage changes with the VF value of the LED. This is in line with the characteristics of the LED and keeps the luminous brightness constant. The LED is greatly affected by the current change, and the constant current drive can be extended The life of the LED; in addition, the luminous efficiency and ...

What are the LED power drive modes?

1. Constant current led drive type: The output current of the constant current drive circuit is constant, and the output DC voltage varies within a certain range with the size of the load resistance. The smaller the load resistance, the lower the output voltage. The larger the load resistance, the higher the output voltage. ①The constant current drive circuit is ideal for driving LEDs, but the pri...

What is the general working mode of led power supply?

LED lighting is a lighting fixture made of light-emitting diodes as the light source. The LED driver power supply is a power supply device used to drive the normal light emission of the LED lighting lamp, and its core is the LED driver chip. Also known as the LED driver LC. Most of the early LED drive power supplies used constant voltage mode, which had many drawbacks. At present, most LED drive p...
