Research output: Contribution to journalArticlepeer-review


A family of offline bridgeless quasi-resonant LED drivers is introduced. The prominent features of the proposed drivers are the capacitive isolation feature, inherent low line-current distortion, and high power factor. The concept is validated by a 30-W prototype operated in the range of 150-200 kHz and 30-V dc output (LED string voltage).
