Diodes Incorporated announced the availability of the AL5822 LED current ripple suppressor, which provides high levels of ripple suppression while maintaining high power factor for commercial and industrial lighting applications.
It is now mandatory to meet regulatory requirements to suppress low frequency ripple (100Hz to 120Hz) in LED lighting applications in many markets, enforced through standards such as the California Energy Commission Title 24. The AL5822 delivers a high level of ripple current suppression in single-stage, high power LED installations, even when triac or PWM dimming techniques are being used to vary the light level. This ensures there is no sign of flicker or strobing across the entire dimming range, while still maintaining a high power factor.
The AL5822 has been designed and tested to comply with the Title 24 building code requirement of less than 30% flicker. The results show that the AL5822 suppresses over 97% of ripple while still achieving a power factor of greater than 0.9 (more info).
