How to define whether the power supply has flicker (flicker) or not?

The general led power supply scheme is single-stage, and the ripple is relatively large, there must be stroboscopic, and generally appear wavy in photographic equipment.


0-10V dimmable led driver 120W


If it is two-stage PF correction, there is no flicker, such as our 0-10V dimming 100-200W led driver Supplement: Regarding the PWM output dimming power supply, the regular bars seen in photographic equipment are currently defined as a kind of stroboscopic. In fact, as long as the output frequency is more than 170Hz, it is harmless to the human body.

The use of photographic equipment in this environment will have a certain impact, so there is a standard for stroboscopic exemption (the output must be ≥3200Hz). After testing, there are still some bars in the 3200Hz output frequency, so we will launch a higher output later Frequency power supply is still under development.

The ordinary non-dimming PF value is about 0.6. It is not single-stage or two-stage. There is no PF correction at all, and they are all LED driver without flicker. The ripple is very small, so small that it can be ignored, but this kind of without PF correction Although low ripple and no flicker, the THD is very high. For some customers who strictly require THD value, such a power supply is not accepted.
